Dear MOAB users, A minor update to the MOAB library is now available. The tarball can be downloaded from [1]. If you are working with release branches in Bitbucket, please use the newly created "5.3.1" tag to get the latest changes. Some notable updates: * Fixes for building on Windows MinGW64 * Adding a mirror for TPL tarballs now at ANL FTP site * Minor fixes for merging meshes by integer tag * Performance improvement for Eigen3 SparseMatrix insertion * A new tool to visualize maps to display DoF coupling between source and target component meshes with a given map file * Read coupling maps in parallel and apply it on existing field with an option to fallback to using PNetCDF * Consistently decompose polygons in parallel so that the order of operations is preserved. This fix ensures results between parallel mbtempest and serial TempestRemap runs return the same map files As always, please do let us know if there are any issues with the new release. Best, Vijay [1] https://ftp.mcs.anl.gov/pub/fathom/moab-5.3.1.tar.gz
