A Load-balanced adaptive mesh refinement for OpenFOAM

Note

If you're using OpenFOAM v2112 or newer, please switch to the v2212 branch. The master branch is for OpenFOAM v2012 and earlier versions (v2106 is not supported). See #6. The Allwmake does this automatically for you now.

This repository extracts library parts from blastFoam which are relevant to load-balanced adaptive mesh refinement for polyhedral meshes while retaining the original commit history; this is not intended as a full port! Only tested features are to be trusted. !!WIP!!

To get started, you can visit the one and only wiki page.

Objectives

• Have a reasonable Load-balanced AMR for 2D/3D OpenFOAM meshes in the ESI fork.
• Support load balancing of Lagrangian particle clouds (not yet implemented).
• Make it easy to include this lib in other projects through submodules/subtrees.

blastFoam is GPL licensed; see the included (original) COPYING.

Quick Notes

• Everything compiles to your $FOAM_USER_LIBBIN with a recent ESI (openfoam.com) version.
• Our favorite refinement cell selector is the coded. Although a wide range of selectors is provided, they are not well tested. So, use the coded refinement whenever possible.
