Example: Defining Internal Forces

The task for this example is to define the sum of internal forces in the y-direction (INTERNAL_FORCE_Y) of the global coordinate system (CS_0) of node group ND_INTERNAL_GROUP_LEFT connected to the element group EL_INTERNAL_GROUP_LEFT.

This task shows you how to:

Define internal forces in Tosca ANSA® environment

  • Apply New > INTERNAL_FORCE on OBJ_FUNC_ITEM_1 or CONSTRAINTS item as shown in the following figure:

Define internal forces in Tosca Structure.gui

  1. Choose Command > DRESP.

    The DRESP menu appears.

  2. Define the internal forces as design response as shown in the following figure:

Define internal forces in Tosca Extension for ANSYS® Workbench

  • Tosca Extension for ANSYS® Workbench does not support this SIMULIA Tosca Structure feature at the moment.

SIMULIA Tosca Structure Parameter File

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

    DRESP
 ID_NAME        = internal_force_response
 DEF_TYPE       = SYSTEM
 TYPE           = INTERNAL_FORCE_Y
 EL_GROUP       = EL_INTERNAL_GROUP
 ND_GROUP       = ND_INTERNAL_GROUP
 LC_SET         = ALL,1,All
 GROUP_OPER     = Sum
 CS_REF         = CS_0
