Default changing porosity

Hi!

I have a problem with a flow trough porous zone... The thing is I need to define the potosity as a function of space and time - the porosity of the surface is not uniform and it also changes every timestep...

Is it possible to define that with UDFs?

Thanks in advance...

hi!

i am also modelling similar problem,but the porosity is needed calculated because it is a melting and solidification problem.defining your problem using UDF is needed further study FLUENT.

Hi!

Well it looks that I have a simmilar problem. The melted mineral wool is falling on the surface and solidifiing. The thickness of the layer changes the porosity of the surface...

Did you work with udfs? which ones

yes.defining the viscosity and resistance coefficient AND temperature hoops using UDF.
