Here is the problem. Somewhere in your mesh, there is a terahedron with all
4 vertices on a fault. This can happen
because

  a) there is a problem in your fault description

  b) You have two faults which get too close to each other

  Thanks,

Another possibility is that there is a bug. We have made a lot of improvements since v1.4.2, so I recommend that you use the current release (v.1.6.1) and see if you still get the same error message.
