unsteady case, how to update the porosity?
 
hi,I'm doing a unsteady case, in the porous zone the porosity have to be updated with time, also with the inner flow conditions. the problem main focus on the initialization of the porosity.
when do the boundary conditions update with a profile udf, before the iteration or after?
