How to do inclined layer in block ROCK?

All geometry is done in blocks ELEME and CONNE (not ROCKS) - see related entries. In particular, variable BETAX indicates the cosine of the angle between a connection and gravity, which needs to be different from 0.0 (horizontal) or 1.0 (vertical) for inclined layers. You can assign one of the three permeability values specified in ROCKS to a connection through variable ISOT.
