  1. Mesh sensitivity was tested for case AAA80, and time step convergence was studied for AAA60. Both models used an ILT permeability of kF = 10-12 m4 N-1 s-1. When reducing the mesh size or the time step the results change negligible, and the computational time is inverse directly affected by the time step size.
