Fortran - CGNS Parallel Output in Polyhedral Mesh #366

I am trying to write a Parallel CGNS output routine for an in-house Fortran90 - MPI solver. I have already implemented a routine for fixed size elements which works.

Now, I would like to extend to polyhedral meshes and it seems that CGNS supports only fixed-size elements (again only in parallel).

Is there a way to circumvent this problem or will there be any CGNS poly-element support in the future?

Since release 4.3.0 there are the functions

cgp_poly_section_write cgp_poly_elements_write_data 

that allow writing of polygonal and polyhedral sections in parallel. Reading is, I think, not possible in parallel though.

Thank you for your quick response.

I run the latest version of the library which was git-cloned and compiled. However, I get an undefined reference to cgp_poly_section_write_f function call (the cgp_poly_elements_write_data_f call is recognized by the compiler).

Additionally, in the function call list of the following documentation site https://cgns.github.io/cgns-modern.github.io/standard/MLL/CGNS_PMLL_library.html#element (element connectivity section), this particular routine is only mentioned for C (and not for Fortran).

Thank you again.
