Face-loops in GAMBIT
 

This is a GAMBIT question:

Looking for help building a macro that can take care of the following:

I wan't to create a face that is made of nx by ny smaller face elements. nx and ny is variables that is different for each case I have. Basically I generate one small face that has to be copied nx times in one direction. Then the nx faces should be copied ny times in a perpindicular direction. The problem is that nx and ny change value for each case....

How is this done macro-wize?
