hm_getorientation

Returns a 4x4 matrix corresponding to the moment directions of the input.

Syntax

hm_getorientation entity_type mark_id ?<option1>=<value1>? ?<option2>=<value2>? ... ?<optionN>=<valueN>?

HyperMesh Tcl Query Command

Returns a 4x4 matrix (16 values) corresponding to the moment directions of the input.

entity_type: The type of entity to query. Valid values are elems, solids, surfs, nodes, comps and parts.
mark_id: The ID of the mark of entities. Valid values are 1 and 2.
comparetype=<value>: The type of comparison when entity_type is comps or parts:; 0 - Consider both FE (elements) and CAD (surfs/solids). Default if not specified.; 1 - Prefer CAD. Use FE when there is no CAD.; 2 - Only CAD; 3 - Prefer FE. Use CAD when there is no FE.; 4 - Only FE

Find the difference between the orientation of two selections of surfaces:

*createmark surfs 1 23-44
set x [hm_getorientation surfs 1]
*createmark surfs 1 56-60
set y [hm_getorientation surfs 1]
hm_getmatrixdifference $x $y

Find the difference between the orientation of two components:

*createmark comps 1 44 45
set x [hm_getorientation comps 1 comparetype=1]
hm_getmatrixdifference [list [lindex $x 0]] [list [lindex $x 1]]

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

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