SPLITGROUP,<group>,<split>,[dir]
This command allows the user to split a group in using the same algorithm that the PANELIZE command uses to split groups. This command only splits the group specified in the first argument. The group to be split can be any group in the model with any element type.
When using the dir argument the split argument will contain the floating point location of the splitting plane in the global coordinate system. Otherwise, the split argument is group number of a shell group that will be used to define the splitting plane. The second group must be shell elements. The command was designed to be used with the WALLFLR command so the first shell in the group is used to define the splitting plane.
