Example: Defining an Reaction Force Design Response

The task for this example is to define a reaction force in y-direction (REACTION_FORCE_Y) of the global coordinate system (CS_0) of node 112072.

This task shows you how to:

Define an Reaction Force in Tosca ANSA® environment

  • Apply New > Displacement on OBJ_FUNC_ITEM_1 or CONSTSTRAINTS item. Define the reaction force as constraint with MAGNITUDE = ABS:

Define an Reaction Force in Tosca Structure.gui

  1. Choose Command > DRESP.

    The DRESP menu appears.

  2. Define the reaction force as design response as shown in the following figure:

SIMULIA Tosca Structure Parameter File

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

    DRESP
 ID_NAME        = my_reac
 DEF_TYPE       = SYSTEM
 TYPE           = REACTION_FORCE_Y
 NODE           = 112072
 LC_SET         = ALL,2,All
 GROUP_OPER     = Max
 CS_REF         = CS_0
