FamVC_ about cgns

[brtnfld]

Depending on the family level, you should be able to use the family APIs: https://cgns.github.io/CGNS_docs_current/midlevel/families.html. FamVC is not a standard definition.

I do use the family APIs, i.e. cg_fambc_read_f, but the BCType parameter is garbage (i.e. things like -1412585528). Do I have to just ignore that data and deal with the errors myself?

[brtnfld]

We need to determine if there is a bug in the Fortran API (or C API) or if it's the CGNS file itself; it should not return garbage. Is the file ADF or ADFH (HDF5)? Are any issues reported by cgnscheck for the file? Did you install CGNS yourself, and did it pass all the tests? The Fortran family APIs are only tested in the examples.

[adrianjhpc]

HDF5, and cgnscheck doesn't complain. However, I'm not checking the error code returned by cg_fambc_read_f, so I'll check that it is not actually telling me it is failing anyway.

[brtnfld]

If cgnscheck passes, it is most likely an issue with the Fortran API. You most likely will not get an error because the C API does not do a sanity check of the bocotype returned. If you are comfortable with C and recompiling CGNS, you could print out the value returned from the C API in cg_ftoc.c (or cgnslib.c if you want to go further into the C library). You could also use the hdf5 tool "h5dump" on the file to see if the contents of the file are reasonable.

What compiler and system is this?
