Use the Control Vol panel to define control volume objects within a model.

 

Subpanels and Inputs


The Control Vol panel contains the following subpanels:

hmtoggle_arrow1Airbag

Use the Airbag subpanel to create the control volumes/airbags using a set of components, elements, or contact surfs.

 

Panel Inputs

Input

Action

name

Enter a name for the control volume.

card image

Select a valid card image.

entity selector

Select the elements, sets, or contactsurfs that you wish to include in the control volume definition

edit

Click edit to review the control volume card previewer content

 

hmtoggle_arrow1Reference Geometry

Use the Reference Geometry subpanel to define a reference geometry for the nodes of an airbag.

Each reference geometry holds the IDs of the nodes selected as well as their original nodal location.  After you create the reference geometry, you can manipulate the original mesh (that is rotate, deform, scale or translate the mesh to simulate airbag folding or other conditions).  When you review reference geometry, it displays the original nodal locations at the time the reference geometry was created. (In this way, the reference geometry definition can be used to preserve IMM information for solvers that have these features implemented.)  If you delete a node or element that is a member of a control volume, it also deletes the control volume definition.

Some typical applications for a control volume include:

Single chamber FE airbag models (define solver specific parameters on the card previewer)
Tire models
Fuel tank models
