    Porous Media Drastically increases solve times

    Grant Smith

      I have a system level model that I am using to evaluate recirculation effects.

      The simulation will solve in about 20min with out using porous media. When I unsupress the porous media element the simulation then takes about 20 hours. If I then supress the porous media the simulation then goes back to 20 min.

       

      Is this normal?

       

      I created a simple wind tunnel model and the run times were 13 sec no porous media and 50sec with porous media. I am using a pressure vs resistance curve.
