Description

Splits shell elements using various methods.

Inputs

method
  • Defines the method used to split the elements. Valid values are:
  • 2 - Divide quads, shortest diagonals
  • 12 - Divide quads, aligned diagonals
  • 21 - Split all sides
  • 22 - Divide quads, unionjack diagonals
  • 23 - Midpoint, to quads
  • 24 - Midpoint, to trias
  • 32 - Divide quats, largest angle diagonals
Add 4 to any method to enable the use of an inferred surface if no geometry exists. Add 100 to any of the "divide quad" methods to reverse the split direction.
mark_id
The ID of the mark containing the elements to split. Valid values are 1 and 2.

Examples

To split quad elements 1-10 using unionjack diagonals:

*createmark elems 1 1-10
*splitelements 22 1

To split quad elements 1-10 using unionjack diagonals and using an inferred surface:

*createmark elems 1 1-10
*splitelements 26 1

Errors

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