Description
The current user guide for AdditveFOAM discusses the use of zoltan for load balancing during adaptive mesh refinement, however zoltanRenumber appears to be deprecated for OpenFoam-14, so zoltan is no longer available for selection as a distributor. Using zoltan as the distributor under decomposeParDict will result in an error in additiveFoam if used. Are there any good alternatives here for load balancing with adaptive mesh refinement?
You can find the associated commit for removal of zoltanRenumber in OpenFOAM here: https://github.com/OpenFOAM/OpenFOAM-14/commit/4b6b4924082f3499c99687fd45108410e59d1788
