Hello,

I'm trying to run a case where mesh partitioning is required and i have the following error:

/home/cenvinzf@coria.fr/Desktop/code_saturne_coria-HuuTri_dev/code_saturne/src/mesh/cs_partition.c:2934: Fatal error.

Partitioning with METIS required but neither
ParMETIS nor METIS is available.

Yet, the code has been installed including ParMETIS library, so i can't really figure out what might be causing this issue. Does anybody have a guess?

Thanks for the help,
Francesco

Hello,

Looking at your install_saturne.log file, it seems that METIS/ParMetis support was not detected correctly, so you may have an issue in the provided path or a compatibility issue (you would need to check the config.log file in the code_saturne build directory to determine the details).

In any case, you should probably be fine without ParMETIS, using either PT-Scotch or the built-in space-filling curve-based partitioner (with best results usually obtained with PT-Scotch, but this depends on the mesh).

Best regards,

Yvan
