Description

This command updates the parameters of a topology design variable.

Inputs

name: The name of the topology design variable.
mindim: The minimum diameter of members formed. A value of 0 indicates that minimum member size control is not active.
maxdim: The maximum diameter of members formed. A value of 0 indicates that maximum member size control is not active.
stress: The stress constraint upper bound. A value of 0 indicates that a stress constraint is not active.
mesh_type: Flag to indicate the mesh type. Valid values are:; 0 - Mesh type is inactive.; 1 - Mesh is not aligned with neither draw direction nor extrusion path.; 2 - Mesh is aligned with draw direction or extrusion path.
fatigue_type: A flag to indicate fatigue constraints. Valid values are:; 0 - No fatigue constraint.; 1 - Fatigue constraint specified as lower bound on damage.; 2 - Fatigue constraint specified as upper bound on life.
fbound: If fatigue_type is 1, this is the lower bound on damage. If fatigue_type is 2, this is the upper bound on life.
mingap: Minimum gap value. If maxdim is not active, should be set to zero.

Example

To update the parameters of a topology design variable named dtpl1, with a minimum member size of 0.5, stress constraint of 25 and damage limited to 10, with minimum gap value of 0.5:

*topologyparametersupdatewithmingap "dtpl1" 0.5 0.0 25.0 0 1 10.0 0.5

Errors

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:

if { [ catch {command_name...} ] } {
   # Handle error
}
