Optimization Parameters For Mode Tracking

This section describes how to control mode tracking in sensitivity-based bead optimizations.

Mode tracking is controlled by two optimization parameters:


MODETRACKING = <on/off>, <node_group>
MODENUMBERS  = <number_modes>

Mode tracking is activated by setting the optimization parameter MODETRACKING = ON. The second item on MODETRACKING can be used with a (small) node group that is used for the mode tracking, which can improve performance.

By default, the mode tracking of SIMULIA Tosca Structure takes 5 modes into account, but this can be changed by the item MODENUMBERS = <number_modes>.

Important: The value should not be set too high because of computational effort.
