Fluent PUMA 2.5D not working

    • vedama

      I have a one-cell thick extruded (rotated) mesh but I get this error when trying to run the PUMA 2.5D Adaption. My mesh is one layer of prismatic cells, and both front and back faces are type symmetry. I only have one cell zone. Why is this happening? How do I overcome this?

      ~~~~~~~~~~~~~~~ Adaption is not permitted for the current mesh ~~~~~~~~~~~~~~~


      - Selected adaption mode: PUMA (2.5D)

      is inappropriate for the current mesh

      - The PUMA (2.5D) method requires the following:

      ~ The mesh must be created with one layer of

      prismatic cells, and the front / back face

      zones must be of type symmetry

      ~ If multiple cell zones are present, each

      cell zone must have a separate front / back

      set of symmetry face zones

      What exactly am I looking for? I'm well versed with the concept of PUMA adaption and I can do 3D, no issues. I don't want 3D. I want 2.5D to work.
