Hi all, Just wanted to let you know that we merged a pretty large branch (feature/hdf5-mesh-4, merge request 900) into master yesterday. This sets the groundwork for a new HDF5-based mesh geometry format to address issues we have with partitioning large meshes at runtime. Although we've taken the usual steps to see if anything major is out of place (regression tests, profiling), a large amount of work was done in SpatialDomains, so it's possible issues might arise in the next few weeks. If you do notice problems then please let me know either on the users list or, preferably, on a gitlab issue! Many thanks, Dave
