Requires:

• gnuplot, {lang}[GCCcore/12.2.0] gnuplot v5.4.6, libcerf v2.3, libgd v2.3.3, ... #17483
• SCOTCH, {math}[gompi/2022b] SCOTCH v7.0.3 #17459
• ParaView, {vis}[foss/2022b] ParaView v5.11.0 w/ Python 3.10.8 #17451

OpenFOAM's parallel decomposition with SCOTCH requires a non-threaded MPI build of SCOTCH. Has this changed with version 7.0.3 ? Or should it instead depend on a no-thread version of SCOTCH ?

@mboisson Indeed, there are still some problems with threaded scotch in some setups. Therefore I switched back to old-style scotch easyconfig (see last commit for #17459).

hum, in my local build, I have to use threadmpi = False:

but I don't see that in your recipe

I would suggest bumping to CGAL 5.x. You need to use c++14 to build with CGAL 5.x.

CGAL 5.x can be installed at the SYSTEM level, and with the CMakeMake EasyBlock (rather than the custom EasyBlock), since it is now header only.

I installed our OpenFOAM v2212 with toolchain gofb, and I used CGAL 5.2.4 (this is the last version that can be installed with the custom cgal.py EasyBlock, because it is the last version which can generate compiled libraries, and I did not want to modify the EasyBlock, but a colleague installed CGAL 5.5.2 with the CMakeMake EasyBlock instead).
