pato is on a distinguished road
Iīm simulating porous media. First of all i didnīt put any value for permeability or resistance loss coefficient, having the process a good convergence.
When changing the permeability parameter, it is much more difficult to get convergence, having floating point problem. MY question is, what value does the solver take when i donīt put any value in the box of permeability?and for resistance loss coefficient?
that would help me to see in what range of values the model has good convergence.

I do not know. If you look in the <CFX_ROOT>/etc/VARIABLES you might get some information about limits and other restrictions.

Other than that, I would just recommend sweeping a range of permeabilities and finding out for your self what works and what does not.
