Hello community!

I am new in SU2, I would like to do a simulation of a sphere in hypersonic regime to compare with those results obtained form a code developed by ourself. Is "Symmetry boundary marker" the boundary condition that I have to use for the axis of symmetry? I suppose so, but just want to be sure.

Thank you very much in advance!!!!

Hello akun646,

You have a few options for running axisymmetric cases with SU2.

1) You can run a 3-D simulation with two symmetry planes that intersect at the axis of symmetry. If you choose this approach, SU2 does not have the logic to detect the polar singularity, so be sure that any references to the polar singularity are removed in the mesh file and apply the symmetry boundary conditions to the two faces as normal.

2) You can run a 2-D axisymmetric simulation. If you choose this approach, provide a two-dimensional grid, and be sure that the AXISYMMETRIC tag is set to 'YES' in the configuration file. Then apply the symmetry boundary condition along the symmetry axis as normal.



Good luck!
-Sean

Hello Sean,

the idea is to start with a 2D axisymmetric model. Thank you very much for your help, it is truly helpful!!
