3. DEFORM-F23 v10.2, Integrated-2D3D v10.24. Integrated-2D3D v11.0 (beta, on PC only)5. DEFORM License Manager v3.0.3

DEFORM v10.2 comes with an updated License Manager 3.0.3. To run DEFORM v10.2 and DEFORM v11.0(beta), the minimum

required version of the License Manager is 3.0.2 This version of DEFORM v10.2 requires a password for v10.2.

DEFORM v11.0(beta) included in this release can also run using theDEFORM v10.2 password.

Due to the major enhancements in DB structure to include new

features and functional improvements resulting from several ongoingdevelopments, database structure in version11 is not compatible withv10.2. V10.2 system can not process or run v11.0 database.Although v10.2 can be run in v11.0 by creating the required –ve stepin v11.0 pre-processor, it is generally not recommended to mixdifferent versions in the same database. A database conversionfacility (from 10.2 to 11) will be provided when the DB structure in v11is finalized..

Details on the license manager version, product version andpassword compatibility details are given at the end of this document.

DEFORM v10.2 GUI related updates

1. (2d v10.2) Sliding die definition between rigid objects can now handleinter-object relations for non-consecutive object numbers. Geometrypoints of the slave die must see a master geometry segment for the rigiddie contact to be active. This reported issue was in DEFORM v10.1,where the rigid dies were seen to penetrate each other even with amaster-slave relationship defined.

2. (3d v10.2) 3D geometry import now allows the file name extensions for.PDA and .PAT formats. The reported issue was in DEFORM v10.1,where geometry files with only .PDA extension were allowed.

3. (3d v10.2) A stability issue related to handling point-tracking points whenthe object splits into two has been addressed. The reported issue was inLinux version of DEFORM v10.1, where the system failed to locate thenew position of the tracked point on the split object.



4. (3d v10.2) An issue related to path movement definition in local frame hasbeen addressed. The reported issue was in DEFORM v10.1, where pathmovement was defined in local frame as a function of time.

5. (3d v10.2) A vector plot display issue has been addressed that occurred

when the display had been zoomed and animations were saved. Thereported issue was in DEFORM v10.1, where the vector display was seton a sliced plane, and user saved animation in a zoom window, the vectorsize was not properly scaled to the new window setting.

6. (3d v10.2) The issue has been addressed relating to saving the strainscaling data between the rolling passes when user opens, saves andcloses the project file. The reported issue was in the Shape Rollingmodule of DEFORM v10.1, where the user visited a project file and savedthe master and project files, the strain scaling information was notcorrectly saved.

7. (2d3d v10.2) Capturing work space image and capture image to clipboardissues have been addressed. The reported issues were in DEFORMv10.1, where users were required to avoid the use of ‘Aero theme’ in Vistaand had to opt for ‘Window 7 basic’ on Win7 PC operating systems.

8. (3d v10.2) Local and global time are now correctly handled in MO2 andMO3 modules when operation cycles are used. The reported issue was inDEFORM v10.1, where global time after each operation was getting set tozero when operation cycles were used.

9. (3d v10.2) Velocity and symmetry boundary conditions are now retainedfor multi pass ALE shape rolling symmetric models. The reported issuewas in the shape rolling module of DEFORM v10.1, where the velocityboundary conditions at the beginning and end surface of the workpieceand the symmetry conditions were getting mixed up when run time datawas generated from one pass to the next.

10. (3d v10.2) Improved data checking when sliding die definition is used inthe shape rolling models. The reported issue was in DEFORM v10.1,where sliding die movement data was defined on a symmetric model withone roll and workpiece. The data checking was blocking the databasegeneration indicating insufficient movement data.

11. (3d v10.2) An issue related to extracting coating mesh information hasbeen addressed. The reported issue was in DEFORM v10.1, where amodel keyword file was loaded into the preprocessor (with coating meshand coating materials defined) and the coating mesh information was notcorrectly extracted from the loaded file.



12. (3d v10.2) Inconsistency between 2D and 3D has been addressed dealingwith plotting principal stress summary graphs. In DEFORM v10.2, whenmin/max summary plot on principal stress is requested in the postprocessor, the plot contains two curves that include minimum of minimumprincipal stress (Sig3) and maximum of maximum pricipal stress (Sig1).

Issue was reported in DEFORM v10.1, where both of the curves plottedmaximum principal stress. (i.e min/Sig1 and max/Sig1).

DEFORM F2, F3, F23 related updates

1. (F2, F23 v10.2) An issue has been addressed dealing with the wrong unitsystem being displayed in load-stroke graphs. This bug was reported inDEFORM v10.1.

2. (F2, F3, F23 v10.2) Consistency issues were addressed in handling theoperation type while adding additional operations to an existing project or

database. The reported issue was in DEFORM v10.1, when the firstoperation was set up by loading a database of a hot forming operation,subsequently added operations were not retaining the hot forming settingscorrectly.

3. (F23 v10.2) A bug has been addressed relating to keeping the meshhidden while flownet and state variable are displayed for several steps.The issue was reported in DEFORM v10.1, where the hidden mesh turnedback on when the step was changed.

4. (F3 v10.2) The handling of the positioning dialogs was improved whenobject geometry is imported. The issue was reported in DEFORM v10.1,where the object positioning options were not available for the importedobject geometry.

5. (F2, F3, F23 v10.2) Force interpolation procedures were improved andnow do not require users to specify any tolerance values for forceinterpolation for die stress analysis. The system now adaptively computesthe tolerance value to achieve optimal force balance between theworkpiece and dies.

6. (F23 v10.2) An issue related to maintaining the vector size whendisplaying vector plots across the steps has been addressed. Thereported issue was in DEFORM v10.1, where the size of the vector wasnot properly maintained during the animations and on section plots.

7. (F23 v10.2) The handling of local and global viewport information wasimproved. Local viewport settings are now maintained in the currentsession, while the global settings are maintained across the sessions. Thisissue was reported in DEFORM v10.1, indicating the loss of local viewport



settings once the user switches from one project to the next in the currentsession.

DEFORM v10.2 FEM related updates

1. (3d v10.2) A memory leak has been addressed that was found in theDEFORM v10.1 64 bit FEM engine in MPI mode on Linux operatingsystems.

2. (3d v10.2) On both PC and Linux, a consolidated 3D FEM engine hasbeen implemented. The Task Manager will now only display multiple MPIinstances of DEF_SIM.EXE, instead of either DEF_SIM.EXE,DEF_SIM_P4.EXE or DEF_SIM_P4P.EXE depending on the MPI setting.

3. (3d v10.2) Semaphore cleanup procedures on Linux operating systemshave been further improved in DEFORM v10.2. More checks and cleanup

procedures have been added to the command scripts used in running themodel. DEFORM v10.1 had some reported issues of left oversemaphores causing failure of MPI jobs. This reported issue was morepronounced in cluster environments.

4. (3d v10.2) The text-based data extraction module on Linux(DATEXT3.EXE) has been updated to handle database structurechanges. The reported issue was in DEFORM v10.1.1, effecting usersrunning their own automatic text-based procedures to process results frommultiple DB files without visiting GUI modules.

5. (3d v10.2) An issue has been addressed dealing with increasing elementstrain values in the rigid zones while using nodal strain definition. Thisissue was reported in DEFORM v10.1.

6. (2d, 3d v10.2) A bug was fixed in handling the die velocity and statevariable updating for plastic objects while the press is stretching due tolow stiffness. A message will now be flashed accordingly when theresulting die velocity is approaching zero (due to press stretch).Inconsistencies due to resulting energy computations were alsoaddressed. In DEFORM v10.1, the reported issue was that even thoughthe die velocity was zero, state variables were seen to accumulate.

7. (2d,3d v10.2) Handling of state variable updating was improved for plasticobjects under low press stiffness and large press. This update alsoaccounts for more accurate energy and die load predictions. Issuesreported in DEFORM v10.1 included 1) state variable change while thepress was stretching without any workpiece deformation, and 2) aninconsistency between the energy computations based on the die velocityand load compared to that of post processor computations.



8. (2d, 3d v10.2) A bug was fixed in handling the grain recrystallization

kinetics based on average deforming strain rate and critical strain rate.This DEFORM v10.2 fix ensures that when the deforming strain rate isabove the critical strain rate, material points undergo metadynamic

recrystallization correctly. Examples to illustrate this feature are includedunder the HeatTreatment folder in DATA folder.

9. (2d, 3d v10.2) A bug was fixed in handling the material diffusion coefficientwhen models 3 or 4 were used (i.e D=C1(T)exp[C2(T)A] orD=C1(A)exp[C2(A)T] ). Issue was reported from internal testing forDEFORM v10.1.2+, where it was found that the function data handling forthe coefficients C1 and C2 in these two models was not correctly handled.

10. (3d v10.2) In DEFORM v10.1 version, there was a user report indicatingdifference in model thermal response compared to 3d v6.0 with tet mesh

models. The following is a discussion of this issue.In 2002 (3d v3.1.2), a special technique was introduced to minimizethe effects of tet mesh topology on thermal behavior. This remained asthe default setting until version 3dv6.0. Starting in 3d v6.1, based on usercomplaints and further internal testing, this setting was made conditionalto exclude the models with internal deformation heat or heat flux boundaryconditions. Users can override these settings using the control fileTSMOOTH.DAT in the working folder. This would turn off thermalsmoothing on tet mesh models. When the first line in the DAT file is ‘2’smoothing will be turned on. From 3d v6.1, an additional facility wasadded to enable thermal contact when a single slave node comes in tocontact with master segment. To turn off this feature user can placeTSGLCNT_OFF.DAT in the working directory.

11. (3d v10.2) Improvements were used in handling the penalty number whensymmetry plane boundary conditions were used. The reported issue wasin DEFORM v10.1, where under specific conditions (large objects withcoarse elements and symmetry velocity boundary conditions defined) biasin the deformation stress field was observed. In DEFORM v10.2, this issuehas been addressed by adopting a consistent penalty approach forhandling both the velocity and symmetry boundary conditions. Morestudies and improvements are underway to make this penalty numberhandling fully adaptive.

12. (3d v10.2) Issues have been addressed related to mean stresscomputations for 3d elastoplastic models. The reported issue was inDEFORM v10.1, when nodal stress definition was used, mean stresspredictions were wrong in spring back models following forging. UsingDEFORM v10.1, the only work around for this issue was to use elementstress definitions instead of nodal definitions.



13. (3d v10.2) Issue has been resolved dealing with stress computationswhen a model has multiple elastoplastic objects. The reported issueexisted in DEFORM v10.0 and v10.1, and the problem was caused by afundamental change in the element local number handling done in

DEFORM 3Dv6.1.

14. (3d v10.2) Issue in handling deformation step size defined as a function ofstroke across remesh steps has been addressed. The reported issueexisted up to v10.1.2, in which the step size used for the first step afterremesh was wrong. This has been addressed in DEFORM v10.2.

15. (3d v10.2) Issue related to rotational axis update for objects defined withtranslation and rotational movements has been addressed. The reportedissue was observed in v10.1.2, where in position of rotational axis was notupdated for additional translation when defined for the same object.

16. (2d v10.2) Issue in updating the stress components for elastic plane stressmodels has been resolved. The reported issue was observed in DEFORMv10.1.2 and was caused by code changes were implemented intoDEFORM v10.1.2 to compute elastic sintering shrinkage.

17. (2d v10.2) 2D FEM engine can now handle induction heating models withdual frequency input data for current frequency. For 3D FEM engine thecorresponding functionality is available in v11.0(beta). Example modelsare provided in the Induction Heating sub folder of DATA folder.



DEFORM v11.0(beta) updates (for PC only)

1. (3dv11.0 beta) Updated version of Next Generation Post processor.

2. (3d v11.0 beta) Resistance heating functionality has now been

implemented in DEFORM v11.0. This functionality is now available forboth brick and tet mesh models. New examples have been added to theDATA folder.

3. (3d v11.0 beta) New options are provided in computing nodal pressure.Considering the orientation of the polygons in contact with the die and thecontact conditions, this version allows users to compute both upper anslower bounds on the pressure computations in post processor.



4. (3d v11.0 beta) Mesoscale modeling capabilities have been developed inthe DEFORM system to model the behavior of microstructure evolution.For given initial nodal microstructural parameters and definedrecrystallization kinetics, evolving parameters such as grain size, numberof grains, dislocation density and resulting instantaneous flow stress can

be computed using this functionality. (Material data: Grain)

5. (3d v11.0 beta) System improvements have been made to model theextrusion process. These improvements include an improved FEM engineand an updated template to generate the model details required to carryon the extrusion computations. This functionality is undergoing continuousimprovement and updates will continue to be available.



6. (3d v11.0 beta) An improved Ring Rolling system is provided to setup theinitial the model with deformation history from the previous operation. Thisimprovement allows users to import a 2D model with deformation andthermal history and setup a 3d ring rolling process model.

7. (3d v11.0 beta) New D3D system (Digital 3 Dimensional Micro Structure),that allows multi-dimensional damage modeling capability (model #11) hasbeen implemented. Within one damage model user can define initial dataand evolution of micro void size, number of micro voids, fraction ofcoalescence and total porosity at the element level using this new microvoid damage model. This model is designed to operate on six pre-definedkey files representing current specimen structure and is designed tohandle only the crack opening mode.(C:\Install_path\v11.0_Beta\DEF_GUI_D3D.exe)

8. (2d v11.0 beta) Torsional elastoplastic modeling capability has beenimplemented. Up to DEFORM v10.2, this was only available for rigidplastic models.

9. (2d v11.0 beta) Interface heat transfer coefficient handling from advancedBCC has a reported issue in 2d v10.1.2, making it non functional whenadvanced BCC is defined on multiple boundary segments. This issue hasbeen addressed in 2d v11.0 beta.



10. (2d3d v11.0 beta) An integrated machining distortion module has beenimplemented. The user needs to select either 2d mode or 3d mode to startwith and this product has no 2d3d converter yet. This new system canhandle multiple operations and multiple passes within each operation. Thismodule can read existing 2d machining distortion project files while in 2dmode. More features have been added with respect to boundaryconditions, including pressure and distortion free boundary conditions.

11. (2d3d v11.0 beta) An improved 3D geometry tool now has basic morphingtechniques which adds great design flexibility for parametric model design.Geometry morphing allows one primitive geometry to change into anotherthrough interpolation. Morphing can also work on design features withuser-defined weighting parameters to guide the shape evolution within theconstraints imposed on the geometric features.

System related notes:

1. (2d3d v10.2) Actively running DEFORM jobs now do not allow the systemto go into sleep/standby mode regardless of the system settings. Thereported issue was in DEFORM v10.1 and v10.0 on PC operating systems

where long running jobs were facing runtime and license issues when thesystem went into standby mode due to long idle time at the keyboard.

2. On PC operating systems (XP, Vista and Win7), it is required that the userinstalls Microsoft Visual C++ 2008 SP1 Redistributable Package (x86) andPower Point 2007 to be able to generate PPT file animations from withinthe DEFORM system.

3. Issue related to importing DEFORM generated .wmv file into a PowerPointfile has been addressed. This fix is now verified for PowerPoint 2003(PC),PowerPoint 2010(PC) and PowerPoint 2011(Mac).

4. User routine support is discontinued for Absoftf90 versions v7.0 and v7.5

5. For both 2D and 3D user routine support now includes Absoftf90 v9.0 andv11.0. Corresponding object files, build scripts and batch files areavailable in the product installation folders (\UserRoutine\DEF_SIM under2D and 3D paths). 64 bit user routine support for PC is only available withAbsoftf90 v11.0.

6. On Linux operating systems, 64 bit FEM support is available only forCentos 4+, Centos5+ and Suse Enterprise Linux Desktop (Suse11)operating systems.

7. Batch Queue and simulation server related Issues reported on Linuxoperating systems, have been addressed in DEFORM v10.2. Issue wasreported in DEFORM v10.1 where in, it was observed that batch jobsubmission faces significant delay even though license is available.

8. For the multi processor environments on PC compared the previousrelease, there is no change of Mpich versions used in DEFORM v10.2.Unless these are installed with earlier versions it is now mandatory toinstall 32 bit Mpich1 v1.2.1 for 32bit machines and additional 64 bitMpich2 v1.2.1 for 64 bit machines.
