*shelloffset

Offsets shells along their element normal direction.

Syntax

*shelloffset mark_id corner_type distance_type distance offset_type

Type

HyperMesh Tcl Modify Command

Description

Offsets shells along their element normal direction.

Inputs

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.

Example

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

Errors

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:
if { [ catch {command_name...} ] } {
   # Handle error
