HyperMesh Tcl Modify Command

Swaps the main and secondary entities of groups.

Note:

In OptiStruct, if secondary is a set of nodes, on swapping it is converted to set of elements.
In Samcef, it is used to swap main-secondary entities of groups MCT and STI. New main and secondary entities are created on swapping based on the entity types supported specific to element type and contact type.

mark_id: The ID of the mark containing the groups to update. Valid values are 1 and 2.

Swap main and secondary entities of groups with IDs 1 and 2:

*createmark groups 1 1 2
*swapcontactmainsecondary 1

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

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