Scalable Interfaces for Geometry and Mesh based Applications

MOAB Release 5.1.0

Posted by in MOAB, News, SIGMA

The MOAB v5.1.0 release includes some significant feature additions to support coupled multi-physics climate applications. Details on compatibility of the different tools and dependent libraries are available separately and all questions can be directed to [email protected].
Source tarballs can be obtained from either the Bitbucket repository or through the ftp site. For more build instructions, go to the downloads page.

Table of contents

MOAB Version 5.1.0:

A. Features

  • PR #399, #406, #408, #410: Updates for E3SM workflow to support online remapping computation for climate applications through interfaces to TempestRemap library. Major additions to expose online remapping capabilities by computing exact intersection between unstructured meshes on a sphere, and providing projection weight operator computation through interfaces to TempestRemap for both scalar and vector solution fields with conservation and/or monotonicity constraints. While the primary application target is E3SM for this particular feature addition, the bulk of the interfaces added in this PR can be reused in other coupled physics simulations as well.
  • PR #403: Updates to Cython file generation process in PyMOAB. We’ve done away with static `.cpp` files in the project and are now relying on users having a Cython installation greater than 0.26 on their machine. This helps us with python 2/3 compatibility issues as well as superfluous re-compiles of libraries.

B. Enhancements

  • PR #376, #365: Updates to PyMOAB to improve the Cython interaction and Python3 compatability.
  • PR #397: Consistent CMake configurations for downstream apps
  • PR #404: Update RTT reader to support v1.0.1 specs
  • PR #391, #401: Delete volume/surface OBB trees and restore OBBs from file
  • PR #370: Several improvements in the GeomTopoTool implementation.

C. Fixes

  • PR #363, #398: PyMOAB tag and skinner test fixes
  • PR #364: CMake configuration updates to not always require Fortran for BLAS/LAPACK linkage
  • PR #362: Several semantic and memory leak fixes due to Coverity, cppcheck and valgrind
  • PR #364, #366, #368, #373, #374, #375, #379, #381, #382, #384, #387, #388, #389, #400, #407, #409: Several miscellaneous configuration updates for both autotools and CMake workflows
