Feature request: HDF5 and therefore HPC compliant export format like XDMF in addition to MED
Since MED major versions are not interoperable, two programs which are compiled with different versions of MED library are also not interoperable although both supporting the MED format. Since MED consists of HDF5 data and I am not aware that GMSH supports the HDF5 format in other mesh formats, I request the export/import ability of GMSH for HDF5 mesh formats like XDMF due to their HPC compliance. (I.e. the reading and writing via parallel threads and saving of data in the range of gigabytes without drowning the RAM or the performance of the system too much.)
TL;DR:
- MED is an HDF5 and HPC compliant format which is incompatible between major versions
- HDF5 is suitable for large meshes in terms of RAM and performance (due to parallel threads) also for small systems
- Request for implementation of another HDF5 format like XDMF
Thanks in advance and best wishes Johannes
