Dear All,

I am modeling a porous cone (porosity =62%) material surrounded by fluid (air), the cone surface is also porous and is not covered by any layer other than fluid. In this situation can any 1 guide me how to give the boundary conditions, In my first simulation I have mentioned the cone layers as ''walls with no slip condition'' if I want to make this porous as mentioned above, do I need to use any udf's.

Please provide me help.

Thanks
