*freeshapegridconstraintsupdatewithsetoption

Updates the grid constraints of a free shape design variable.

Syntax

*freeshapegridconstraintsupdatewithsetoption mark_id name ctype syst_id x y z update_flag set_id

Type

HyperMesh Tcl Modify

Description

This command updates the grid constraints of a free shape design variable that corresponds to a DSHAPE card. The grid constraints on the design variable can be updated either by directly selecting nodes or by pointing to a nodal entity set.

Inputs

mark_id
If nodes are used in updating the design variable, this represents the mark ID containing those nodes. If set to 0, set_id will be used.
name
Name of the design variable to update.
ctype
The type of constraint applied:
  • 1 – Grid is fixed.
  • 2 – Grid is forced to move along the vector specified by the x, y, and z components.
  • 3 – Grid is forced to remain on a plane whose normal is determined by the x, y, and z components.
syst_id
The coordinate system ID in which the x, y, and z components are resolved.
x, y, z
Values are defined based on ctype.
update_flag
Flag that indicates how the grid constraints must be updated:
  • 1 – Add the selected nodes or nodal entity set to the currently existing grid constraints.
  • 2 – Remove the selected nodes or nodal entity set from the currently existing grid constraints.
  • 3 – Update the grid constraint with the selected nodes or nodal entity set.
set_id
If a nodal entity set is used in updating the free shape design variable, set_id is the entity set ID. If not required, set to 0.

Examples

To add nodes 1-100 as fixed grid constraints to free shape design variable fsh1:
*createmark nodes 1 1-100
*freeshapegridconstraintsupdatewithsetoption 1 "fsh1" 1 0 0 0 0 1 0
To update the grid constraints of free shape design variable fsh2 to use a pre-existing nodal entity set with ID 25, and force the nodes in the set to move along the vector specified by (5, 10, and 15) in the global system:
* freeshapegridconstraintsupdatewithsetoption 0 "fsh2" 2 0 5 10 15 3 25

Errors

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