lumpedmassflag: Specifies whether to include lumped mass in the COG calculations.; 0 - Exclude lumped mass.; 1 - Include lumped mass.
system_id: The ID of the system to report the COG values relative to.

To get the COG for components 1-5:

*createmark comps 1 1-5
hm_getcog comps 1

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

if { [ catch {command_name...} ] } {
