Greetings, gentlemen.

Is there any way to assign to each cell of the mesh the porosity coefficients and change these values each time step?

In web I found Kamil Kwiatkowski presentation, where it was done by means some "setPorosity" function. I didn't find this function either in OF-1.7.1 or in OF-1.6-ext sources.

Please, help with this problem

Best regards, Aleksey.

HI,

were you able to simulate the problem you have posted that the porosity decreases with respect to time and space.? I am also working on some problem which require this simulation to be performed in which pororsity changes.I will be thankful to you if you provide some guidance if you have solved the issue

Regards
