Do you need to make a vertical fault with real geology in it?
If you need to add a vertical fault with real fault geology, that is a fault plain with material that changes from place to place, you may use the simple attached procedure to modify your GMS geologic model and then use TMT2 to turn it into a Tough2 model. There are many other ways to make a real fault even inclined or fault segments. I will add more files in time...
