how to define the porous region in cfx5.5?

April 9, 2002, 04:09

I use cfx 5.5 to define porous region,but i cannot find some menu like patch in cfx 4.3,how can i do it? and my problem is 2D,how to make it become 2D problem? thanks

CFX-5.5 does not have the same porous region implementation as CFX-4 yet.

To do porous "like" regions in cfx-5.5 you need to create a fluid subdomain. Once you have done this add a resistance source term to the momentum equations. Unfortunately it's only isotropic, and on top of this it's not true porosity because there is no void fractions or anything like that.
