•ADAMS and Easy5 IntegrationMSC.EASY5 + ADAMS External Systems Library (ESL)

•TCP/IP – Based Communication

•C++ Solver Support

•First-order Interpolation

ADAMS/Controls1) MSC.EASY5 + ADAMS External Systems Library (ESL)

Embed your EASY5 models into ADAMS as shared library.Unprecedented access to EASY5 data…

• EASY5 design parameters• EASY5 output results (for use in design objectives)

Perform more comprehensive “What If” analysis…• Design Study, DOE• Multi-disciplinary Optimization

See KB 12270 for example.

Enhanced Integration

Note: Requires MSC.EASY5 2004 R2

ADAMS/Controls2) TCP/IP-based communication

Run co-simulations between different machinesVersatile communication method

• Start ADAMS as a server on one machine on a given port• Then EASY5 (or Matlab) can communicate through that port

Pipes are still available (currently the default)“Distributed computing” now possibleSee KB 12271 for example.

3) C++ Solver supportTake advantage of all the newest technology…

• GCON, Planar part, 2nd Order integrators, etc.See KB 12269 for example.

ADAMS/Controls4) First order interpolation data exchange for co-simulation

Option for selecting a first order hold on both sides of co-simulation• EASY5: 1st Order is the default• ADAMS: Zero Order is still the default

Improved signal quality allows integrator to take bigger steps• Significant speed improvements for many applications

regionsExisting MNFs with undefined (zero) stress can now be ‘optimized’.Addresses performance issues…

• Creates smaller MNFs• Faster post-processing

ADAMS/Flex1) Flexible-Body Swap

You now have an interface tailored for the swapping of flexible bodies.

• Rigid to Flex• Flex to Flex

Use of flexible bodies in ADAMS models is becoming commonplace.Users want an easier way of incorporating flexible bodies into their models.• Alignment and Connections are

are much easier !!See KB 12258 for example.

ADAMS/Flex2) Rigid-Only MNF

ADAMS/Flex will now accept a “Rigid Only” MNF

• Too much engineering time was wasted incorporating FE model into ADAMS

• For instance … Attachment Points– Where are they?– How many are needed?– Do they align with system model connectors?

No longer need a full MSC.Nastran FE solve – just produce without modes.File is much smaller, easy to transfer.Useful as an interim step for building and debugging ADAMS/Flex models.See KB 12413 for example.

Ease-of-UseMSC.NastranADAMSMNF FLEX_BODY=YES, MINVAR=RIGID

ADAMS/Flex3) Auto-Damping (Experimental)

An adaptive damping scheme has been introduced which is step-size based.

• Existing default damping model was often too ‘aggressive’ in damping responses for certain classes of models.

• Running with less damping was too much of a performance penalty

Improved performance of models with less damping.

• Flexible body models can run more robustly.


Ease-of-Use

Less damping…

…and decent speed.

• Many ADAMS models are inherently 2D or contain 2D subsystems.

More efficient than using a PART+PLANAR Joint.

• Runs faster.Fully compatible with all 3D elements and can coexist with an otherwise 3D model.

• Out-of-plane forces are efficiently ignored.

C++ Solver Performance Results for Belt Example

ADAMS/Solver3) Adaptive Jacobian Pattern

GSTIFF can automatically determine when a Jacobian refresh would improve convergence.

• Jacobian evaluation is time consuming.

• Users do not know the ideal PATTERN, which can change as the simulation progresses.

Specify as PATTERN=FSee KB 12260 for example.

4) SMP Parallel ProcessingShorten ADAMS simulation time by utilizing multiple processors in a computer.

• Multi-CPU computers have become a commodity.

• Portions of the ADAMS simulation process can be reliably executed in parallel.

Caveat: Not all of ADAMS is parallelizable, performance gains are model dependent.Expect 15-25% reduction in simulation time with two CPUs.

Note: Requires ADAMS Solver SMP license
