some problems about non-local thermal equilibrium model of porous domain in CFX

dream070141 · December 17, 2014, 04:16

After I finish the computation，in the CFX post，I don't know how to show the solid temperature distribution in porous domain，it can only create the temperature contour of fluid in porous domain

The temperature in the solid part of the porous domain is prefixed with the solid name. For example Solid 1.Temperature..

Thank you for your opinion, I find this situation. if I meet new problem.I will continue ask you

another theory problem. The mesh connection about interface of fluid and porous can only be GGI in this model, but the default method of CFX is automatic. I check the help document, GGI means mesh node on interface are mismatching, why this situation happen in porous domain? How to generate the mesh node of porous domain?(Can I find a explain on CFD theory or equation on porous model?)

Not sure what your concern is. GGI is the methodology used by CFX to handle mismatched mesh interfaces. What the documentation implies is that the only methodology supporting fluid porous interfaces is the GGI methodology. Keep in mind that a 1:1 mesh interface can be treated with the GGI methodology w/o any issues. You can see it as mesh connection with 0 mismatch, right ?

You read further in the documentation, you will see that mesh interfaces with frame change, or pitch change are only supported with the GGI methodology.

what I concern about is that this mismatched mesh is resulted by porous model itself or by the mesh generation in ICEM？Of course, I will read further in the documentation. Thank you again for your guidance.
