actually the permeability is given as 135 md which when converted to resistance comes out to be 7.5e12 (1/m2) so i had given this value as the resistance of solid phase and water resistance as 1000. and there is one issue that when we select secondary phase as solid material from fluent database it is not showing when we are defining it in multiphase model. It is only showing the fluid materials for both phases. The main issue is that porous zone is not detected even when i am giving any resistance values. Please help

Thank you
