Description

This command creates a surface type morphconstraint for the selected nodes with the option of having those nodes either move along the surface or be bounded by it.

Inputs

ntype: Must be set to nodes.
nmark: The ID of the mark for the constrained nodes. Valid values are 1 and 2.
type: 0 - Moves along the surface; 1 - Bounded by the surface; 3 - Remains a set distance from the surface; 5 - Remains its original distance from the surface; +32 - Enable mesh stretching around constrained nodes. Add this value to the type (thus 1, 3, and 5 become 33, 35, and 37).
name: The name of morph constraint.
vec: The ID of the vector created using *createvector. Must be set to 1.
surface: The ID of the surface.
dist: The minimum distance from the bounding surface.
ivec: 0 - The surface normal is used for distance and projection. The nodes will be moved normally to the surface when constraining them or measuring the distance the nodes are away from the surface.; 1 - The vector is used for distance and projection. The nodes will be moved along the vector when constraining them or measuring the distance the nodes are away from the plane.
color: The color of the constraint. Valid values are 1 through 64.

Example

To create a morphconstraint for nodes to move along a surface and projected normally to the surface:

*createmark nodes 1 1 2 3 4 5
*createvector 1 1.0 0.0 0.0
*morphconstraintcreatesurf nodes 1 0 "surface" 1 12 0.0 0 32

Errors

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

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