Hello SU2 community,
I am currently facing an issue with the mesh conversion process from ANSYS to SU2 using Gmsh as an intermediate step. I have created a mesh in ANSYS, assigned named selections, and exported the mesh file in CGNS format. However, when I use Gmsh to convert the mesh to SU2 format and open the resulting mesh file, I notice that there are no markers. Here are the key steps I followed: Created a mesh in ANSYS and assigned named selections. Exported the mesh file in CGNS format. Used Gmsh to convert the CGNS mesh to SU2 format. I expected to see markers corresponding to the named selections in SU2, but they are not present. Has anyone encountered a similar issue before? Am I missing a crucial step in the conversion process? Your insights and suggestions would be greatly appreciated. Thank you in advance! |

Why use gmsh in the conversion? You can just load the cgns directly into SU2. You can then also use SU2 to write a .su2 file if you really want that.
I also have trouble keeping the boundary information, it is a real pain converting meshes. |

"The configuration file doesn't have any definition for marker SURFACE_BODY_1_1_1D!" |

that message means that this boundary name is in the cgns, but you did not define a boundary condition for it in the config file.
you should define a boundary condition for it like Code:
MARKER_HEATFLUX=(SURFACE_BODY_1_1_1D,0) If you did not expect this boundary to be present, then you have to go back to ANSYS and see where this boundary is. |
