  • Import procedures

    In VCS you can always import and use an Object (Cross Section, Beam, Rigid Body, Ruler, Characteristic, etc.) created previously in another VCS Solution. In order to import an object click on File and then on Import. From the drop down list select the Objects from Other Solution option.

    Select a VCS Solution from which you wish to import objects and press Open.

    An Objects Import window will appear on the screen. You will find in it a list of all objects created in the opened Solution. On the right side of the window you can find a read only properties window showing detailed information about a selected object.

    You can select and import as many objects as you wish. After selecting them from the list, click on the Import Selected button. To import objects related with selected ones (e.g. Cross Sections assigned to selected Super Beams) choose Import Dependent Objects. You can also import the entire Solution by clicking on the Import All button.

    The imported objects will be automatically added to the Solution Explorer tree. They will also appear in the 3D view window.

    Import Objects from Other Solution

  • Import data from FE parts

    VCS gives the possibility to import data from FE parts model. The “FE Part” import procedure will be described on an example of a mesh model of a Rocker Panel visible on the right hand side. The beam model consists of two FE elements.

    VCS provides the possibility to set the required units when importing a FE model. After selecting the Import option a new window “Import and Units Conversion Utility” will appear on the screen. In this window you can set the required units of the imported model (length, mass, mass density, pressure / stress, strain).

    To start the import procedure click on File and then on Import. From the drop down list choose the FE Part option. You can select import from Radioss or LS- Dyna.

  • You can also save your setting as default settings by pressing the “set as default” button in the Import and Units Conversion Utility window.

    VCS provides the possibility to set the required units when importing a FE model. After selecting the Import option a new window “Import and Units Conversion Utility” will appear on the screen. In this window you can set the required units of the imported model (length, mass, mass density, pressure / stress, strain).

    Once the units and scaling are defined you can select the Import Data file. After that click on the Import button.

    When import is finished the message box will appear on the screen. Click OK. The Import procedure is now finished.

  • Note that VCS allows importing both 2D Array and 3D Array.

    The 2D Array is used to define the Stress-Strain property of the Material.

    VCS imports also characteristics based on original FE file of curves definitions that describe the Stress-Strain relation including Strain Rate Effect. The VCS counterpart of this material property is the 3D array.

    Additionally VCS has importing possibility for material which stress strain relation was defined in simplified way by entering the values of first effective plastic strain[EPS1], second effective plastic strain [EPS2], etc. and corresponding yield stress values [ES1], [ES2].

    Note that along with the geometry, all information about the Material of the FE elements as well shell thickness data will be automatically imported into VCS. Moreover the import tool creates simultaneously VCS Material basing on FE data. The Material Properties such as Material Constants, Stress – Strain - Characteristics and the Strain – Rate Effects parameters are visible in material definition.

    All imported elements can be easily found in the Solution Explorer Window, in the Imported Objects folder. They will be also displayed in the 3D view window.

    IMPORTANT NOTE:

    The Material is imported only in case when it is assigned to the geometrical component in FE keyword file.

    Due to number of formats of LS Dyna keyword file the properties of imported objects in VCS might have wrong values or the import of properties can be neglected.

  • Import from STL

    In VCS the user has the possibility of multiple file import which means that number of elements can be selected during one import procedure.

    Select as many STL elements as required and click on the Open button.

    All imported elements will be automatically saved in the Solution Explorer tree under the Imported Objects ⇒ Parts folder. They will be also visible in the Solution 3D view.

    VCS offers the possibility to import a STL file format model. In order to start the import procedure click on File and then on Import. From a drop down list select the STL Model option. A new Import and Units Conversion Utility will appear on the screen. In this window the user can set the required units of the imported model (length, mass, mass density, pressure / stress, strain). Note that you can save your setting as default settings by pressing the “set as default” button in the Import and Units Conversion Utility window.

    After defining the import units select the files you wish to import, as it is illustrated in the pictures below.

  • Import from NASTRAN

    VCS provides the possibility to import objects (beams and cross sections) from NASTRAN.

    In order to start the import procedure click on File and then on Import. From the import menu select the NASTRAN option, as it is illustrated in the picture on the left.

    It is possible to import a 3D beam model, arbitrary cross sections and material. Additionally, a number of standard predefined cross sections from Nastran can be imported into a VCS Solution.

    Below you can find the list of Cross Sections which can be imported into VCS as well as images of the original Nastran Cross Sections.

    • BOX • TUBE • CHAN • CHAN1 • CHAN2

  • As a result of the import procedure a Super Beam will be created in the VCS Solution. It will be automatically visualized in the 3D view, and it will be added to the Solution Explorer window, as it is shown in the picture below.

    Additionally a Cross Section will be created, which also can be found in the Solution Explorer tree. The cross section will be named accordingly to its type specified in the Nastran file. An example of such Cross Section can be seen in the picture on the right.

  • Import Cross Sections from HYPERBEAM

    In VCS the User will find the possibility of cross section geometry import. There is functionality of import from the HYPERBEAM software (CSV file format). This functionality is available in the “Import” menu.

    To start the procedure of exporting cross sectional geometry you need to go first to 1D tab and choose “HYPER BEAM” tool.

    Afterwards you should create a new section using the Hyper beam functionalities.

    The import procedure shall be described on the example of A-pillar

    Firstly the A pillar is viewed in the “HYPER MESH” software. This will be the base geometry for incoming actions.

    A cross section needs to be created; therefore the section plane is used to enable edge selection. This plane should be placed in the location, from which we wish to extract a cross section. In the picture on the right the A-Pillar is divided by section plane to extract section lines for each component of A Pillar.

  • Change the display view to make selection of geometry more convenient and select lines by path – as shown in the picture below. Select lines on each component. When all lines are selected press the “Create” button.

    After selecting the required “csv” file, all included cross sections will be imported into VCS. The Cross Sections are going to be added to the Solution Explorer tree.

    In the pictures on the right you can see an example of a cross section created in HYPERBEAM, and its counterpart automatically created in VCS as a result of the import procedure The geometry has been automatically created and can be viewed in the Cross Section Editor.

    All elements are also automatically added to the Solution Explorer tree. Please note that the imported cross section is already divided into segments, plates and points etc.

    The user interface automatically switches to 2D Hyper beam View. You will be able to see the shell cross section composed of number of points connected by lines. The detailed information are available in results window on the right hand side of the screen and editing options form the context menu after selection of the cross section. Now go to File menu and export all shell sections to CSV file. The steps for data preparation are now finished, and you can switch to the VCS software
