*propagatesplithexas
Given a hexa element and two nodes diagonally across a face of that element, splits the hexa according to a set pattern and propagates that split to any hexa adjoining the opposite face of the hexa and so on through the displayed elements of the database.

Description
Given a hexa element and two nodes diagonally across a face of that element, splits the hexa according to a set pattern and propagates that split to any hexa adjoining the opposite face of the hexa and so on through the displayed elements of the database.
Inputs
- splittype
- A number between 1 and 6 identifying the splitting pattern to use.
- 1 - Two pentas (split along the diagonal formed by n1 and n2).
- 2 - Penta & hexa (with the penta to the left of the diagonal).
- 3 - Hexa & penta (with the penta to the right of the diagonal).
- 4 - Two hexas (split from the right of n1 to the left of n2).
- 5 - Three hexas (split from n1 to both sides adjacent to n2).
- 6 - Four hexas (split in a plus pattern).
- startelement
- The starting hexa element.
- n1
- One of the nodes defining the starting face of the hexa.
- n2
- The other node defining the starting face of the hexa.
Example
To split a column of hexas into paired pentas starting with element 205, where nodes 1015 and 1017 are diagonally opposite from each other across one face of the hexa:
*propagatesplithexas(1,205,1015,1017)The hexa elements can be first or second order and need not all be the same order.
Errors
None.
