CFX 4.4 - Porous Model
 

Hello. I tried to model flow inside porous media. When i tried to increase the resistance in the porous media to 1E7 (input velocity = 1E-02), solutions in output file start to fluctuate. i tried to use "Modified resistance treatment", but fail to converage as well. Is there any upper limited for the resistance? or is there other method i can try to improve the solution?

Thanks. joan
