Meshing for perforated pipe buried in porous zone
 

Hello all,

I am using Ansys workbench. What is the best meshing method for perforated pipe surrounded by porous zone? I tried mutizone , but meshing never ends! But when I tried the same model with smooth pipe, multizone works. Is there any issue with multizone and perforation ( though I couldn't find any literature in support of this) ?? And is it something related to RAM of computer ? I am using 6 GB RAM for my laptop.

Any help will be highly appreciated.

Thanks.
