Issues with CGNS formatted mesh in SU2

Hi folks,
Let me preface by saying I'm not sure whether this fits better in the SU2 or Pointwise sub forum. I'll start here. I'm having an issue with running SU2 with a CGNS formatted mesh I created in Pointwise (3D unstructured mesh for a simple blended wing body). The mesh was constructed and exported during an evaluation of the pointwise software, so I unfortunately do not currently have access to it. My config file (bwb.cfg) points to the input mesh bwb.cgns with MESH_FORMAT = CGNS. When I try to evaluate this config file with SU2_CFD I get the following terminal message: !!! Error !!! bwb.cgns is not a CGNS file. Now exiting... I am able to open the mesh file just fine in Paraview. I have SU2 compiled in the latest Ubuntu release, and was sure to use the configuration options: --with-CGNS-lib=/path/to/CGNS/lib --with-CGNS-include=/path/to/CGNS/header when compiling SU2. The cgns library itself is installed correctly to the best of my knowledge. When I run the program cgnscheck on my mesh (built into cgns library), this also throws an invalid file type error. I am very new to SU2 and the cgns format in general, so any help or suggestions are welcome as I'm at a bit of a loss here on how to progress. Thank you kindly, and I'm happy to provide more specific information if needed. |

Turns out Pointwise creates cgns meshes with the HDF5 database. Using the cgns utility cgnsconvert, I was able to switch it to the ADF database, which SU2 was able to recognize.

I am having the same problem, how were you able to switch from HDF5 to ADF?
Thanks, Chay |
