Updating design variables

Use the Update Design Variables command to update the initial values and bounds of the design variable modeling objects in the Simulation file with the current design variable values and bounds of the active Model Update or Model Update Set solution process. This command prepares the work solution to be resolved without modifying the underlying FEM.
