Example: Defining the Volume Design Response

The task for this example is to define the volume design response for the element group DESIGN_ELEMS.

This task shows you how to:

Define the Volume Design Response in Tosca ANSA® environment

  1. Apply New > VOLUME on OBJ_FUNC_ITEM_1 or CONSTRAINTS.

  2. Define a volume constraint in the CONSTRAINT_ITEM dialog as shown in the following figure:

  3. Make sure, MAGNITUDE = REL is closed.

Define the Volume Design Response in Tosca Structure.gui

  1. Choose Command > DRESP.

    The DRESP menu appears.

  2. Define the design response of the type VOLUME as shown in the following figure:

Define the Volume Design Response in Tosca Extension for ANSYS® Workbench

Context:

In Tosca Extension for ANSYS® Workbench a Named Selection is used instead of an element group. This predefined selection can be called later during an optimization setup.

  1. Add a design response to the project.

  2. In the DESIGN RESPONSE dialog, select Base as Category and Volume as Response Type.

  3. Choose the predefined Named_Selection by setting Scoping Method to Named Selection as shown in the figure below:

SIMULIA Tosca Structure Parameter File

  • The resulting command in the parameter file look like follows: 

    DRESP
 ID_NAME        = volume
 DEF_TYPE       = SYSTEM
 TYPE           = VOLUME
 EL_GROUP       = DESIGN_ELEMS
 GROUP_OPER     = Sum
