Questions regarding MPAS 8.4.0

[anias]

Hi everyone,

I have reviewed the new User Guide for MPAS 8.4.0 and had a few questions:

- In the section on online graph partitioning with MP-Scotch, it is mentioned that MP-Scotch assumes edge and vertex weights are uniformly distributed. This made me wonder: does the METIS tool account for variable-resolution meshes?

- From what I have read, there do not appear to be any new physics parameterization options compared to the previous version. Are there plans to introduce new ones in an upcoming release?

Thanks in advance!

METIS accounts for variable-resolution meshes.

It is possible that new schemes will be introduced into MPAS. Please pay attention to the discussion in the upcoming MPAS-WRF workshop for more details.
