HyperMesh Tcl Modify

Offsets shells along their element normal direction.

mark_id: The ID of the mark containing the shell elements to be offset. Valid values are 1 and 2.
corner_type: 0 - Offset the elements using square corners.; 1 - Offset the elements using rounded corners.; 8 - Offset the elements using CFD corners. When this option is specified, an additional mark of surfaces and elements can be specified to specify the geometry to follow.
distance_type: 0 - Offset elements using distance parameter.; 1 - Offset elements using half the element thickness value.
distance: The distance to move the elements. Only valid when distance_type=0.
offset_type: 0 - Offset the elements in the positive normal direction.; 1 - Offset the elements in the negative normal direction.

To offset the displayed shell elements along their positive normal by a value of 0.2, using square corners:

*createmark elements 1 displayed
*shelloffset 1 0 0 0.2 0

To offset the displayed shell elements along their positive normal by a value of 0.2, using CFD corners, with surfaces 1 and 2 as along geometry:

*createmark elements 1 displayed
*createmark surfaces 2 1 2
*shelloffset 1 8 0 0.2 0

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

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