The following parameters might be set:
Move Limit (NODAL_MOVE)
A move limit adjusts the change in the nodal coordinates
per iteration. The relative move limit of the node-based optimization displacement
for each iteration is set by the optimization parameter.
NODAL_MOVE = <real_value>
Default value is NODAL_MOVE = 0.1. The value must be between
0.0 and 1.0. The absolute move limit is the maximum possible optimization
displacement times NODAL_MOVE.
CSA Asymptote Update (NODAL_UPDATE)
The optimization parameter NODAL_UPDATE can
be used to control the update of asymptotes in CSA. The value of nodal
update might be conservative (NODAL_UPDATE = CONS) which is default
or normal (NODAL_UPDATE = NORM).
Sensitivity Calculation (ONLY_DES_NODES)
Tosca Structure.bead
calculates sensitivities only for design nodes:
ONLY_DES_NODES = YES
In the opposite case (ONLY_DES_NODES = NO),
Tosca Structure
is forced to calculate sensitivities for ALL_NODES, which is not recommended.
