HiGuys,


I am trying to run 3D Mesh nozzle from Pointwise to SU2 simulation. Problem is in providing BC or markers to some surfaces because they are additonal refinement connections or surfaces. So in SU2 what boundary conditions I should for those markers which are not really a boundary conditions. I see one boundary conditions as interiors- Can someone help me with this? Because I am having hard time to get this Unspecified markers in SU2 to run.



Attached image of Grid showing in red color (shear layer exiting from nozzle lip). This grid area is just for additional refinement only.

If those markers are not needed, i.e. they are a fictitious internal boundary, the safest option is to remove them from the mesh file (if you do this manually, you just need to delete the entire section for that maker and adjust the number of markers (NMARK=X)

I don't know the exact mesh details here. But if you use baffles in Pointwise for refinement, refinement surface will not show up in BC selector. If it is a separate block, than you need to use edit- Addremovefaces option from the containing block and regenerate the outer block. This was about unstructured mesh. In structured mesh, this problem should not appear hopefully (if made correctly).
