Hello,

during my calculation i change the cell-type from 1 to 2. The cell-type 1 gets the porosity-index of 1, that means it is impermeable. After calculation and after change to cell-type 2 I watch to the velocity-field. I see no velocity. The impermeable must be conserved. But i am sure, the cell-type was changed. Do you have any ideas, what I have made wrong?

Cell type 2 is also porous?

I forgot, the cell-type 2 is impermeable. The alpha value is about 50000. The cell-type 1 is porous with alpha of about 1.e-10.
