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 to with a (small) node group which 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.
