[Nektar-users] Porous Region in nektar++

Dear all We are using nektar to calculate multiple outlets flow problem, and porous region is required in the simulation. In my opinion, when the porous region is applied in computational domain, inertial resistance coefficients and viscous resistance coefficients should be set for the porous region. Is there any instructions that tell us how to set these two coefficients in Condition section of XML session file, or are there other ways to use porous region in nektar++? Best regards, Bin
