>From the previous email:
1. Set Solver type to GENERIC
2. When Meshing, make sure the edge node count is 3 (for midpoints). This should make the face count 8 and the volume count 20 nodes.
This setting is necessary to take advantage of Nektons mid side node support.
3. Use the zones to label faces as Boundary conditions. Select multiple faces if you like. Since the solver is set to generic, just call the BC
anything you like, "Inlet" for example. The Matlab code will ask you "What did you mean by Inlet", where you would input 'v' for a fortran
velocity input. If it is a thermal problem (TBC = 1 in the inputs in rea_write), it will ask for the momentum and thermal BC. In gambit, any
face that is not labeled with a BC type is assumed to be a Wall.
NOTE: The Mesh must be HEX & Edge node count 3!... ONLY works for 3D cases!

Hi Michael,
What is the "list" you are referring to?
Cheers,
Frank
