Example: Defining a Weight Design Response

The task for this example is to define a weight design response for the element group DESIGN_ELEMS and constraining it to 100 Kg.

This task shows you how to:

Define a Weight Design Response in Tosca ANSA® environment

  1. Apply New > WEIGHT on OBJ_FUNC_ITEM_1 or CONSTRAINTS.

  2. In the CONSTRAINT_ITEM dialog, define a weight constraint:

  3. Make sure, MAGNITUDE = ABS is closed.

  1. Choose Command > DRESP.

    The DRESP menu appears.

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

Define a Weight 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 Weight as Response Type.

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

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

    DRESP
     ID_NAME        = weight
     DEF_TYPE       = SYSTEM
     TYPE           = WEIGHT
     EL_GROUP       = DESIGN_ELEMS
     GROUP_OPER     = Sum
