Scalable Interfaces for Geometry and Mesh based Applications

MOAB Release 5.5.0

Posted by in MOAB, News, SIGMA

A new release of the MOAB library (v5.5.0) is now available. The tarball can be downloaded here. If you are working with release branches in Bitbucket, please use the newly created “5.5.0” tag to get the latest changes.

Some notable updates:

– New support for the calculation of scalable, bilinear maps with TempestRemap for Climate problems
– Removed: Mesquite sources and support in MOAB; Several outdated tools (refiner, VTK reader plugin for Paraview)
– Deprecated: ITAPS framework: iMesh interfaces are now only built when requested with `–enable-imesh`. This will be the last version to support iMesh. Going forward, please port your C/Fortran API to use the now-mature iMOAB interface.
– Several fixes, enhancements, and optimizations to make the MOAB library more robust.

Detailed release notes for the 5.5.0 release are shown below.
