Bottom Boundary Conditions

The bottom of the model is fixed in such a way that no movement is allowed on the vertical and horizontal direction. The pore pressure is allowed to fluctuate freely, which means that there is no drainage on the bottom. An example of a fixity command that fixes direction 1 (x), 2 (y), and leaves direction 3 (pore pressure) free is:

fix 925 1 1 0
