Closes #131486.

Please see the new doc section for additional info.

Getting OpenFOAM to build and be usable with nix has been a major headache, because it ships its own build system that has several non-standard assumptions about the environment.

I'm expecting feedback, because I'm sure there's stuff that can be patched/structured/done better, but I'm not sure how.

I have included the latest version at the time of writing, plus the previous version. Often OpenFOAM users stick with a specific version for sometime due to custom extensions. The way the derivation is structured, it can be easily overridden to compile an older version. Going forward I think we should probably only keep the latest 2 versions in nixpkgs.

This work has been sponsored by @nablaflow.
We've been using these derivations in production for ~6 months (x86_64-linux / aarch64-linux).

Things done

• Built on platform(s)
  • x86_64-linux
  • aarch64-linux
  • x86_64-darwin
  • aarch64-darwin
• For non-Linux: Is sandboxing enabled in nix.conf? (See Nix manual)
  • sandbox = relaxed
  • sandbox = true
• Tested, as applicable:
  • NixOS test(s) (look inside nixos/tests)
  • and/or package tests
  • or, for functions and "core" functionality, tests in lib/tests or pkgs/test
  • made sure NixOS tests are linked to the relevant packages
• Tested compilation of all packages that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review rev HEAD". Note: all changes have to be committed, also see nixpkgs-review usage
• Tested basic functionality of all binary files (usually in ./result/bin/)
• 24.11 Release Notes (or backporting 23.11 and 24.05 Release notes)
  • (Package updates) Added a release notes entry if the change is major or breaking
  • (Module updates) Added a release notes entry if the change is significant
  • (Module addition) Added a release notes entry if adding a new NixOS module
• Fits CONTRIBUTING.md.

I recently found out that a dependency's derivation (scotch) has recently been split out into $out and $dev.
This derivation still compiles but fails to see it and use it, resulting in a crash at runtime on a subset of binaries.
I will try to figure this out soon, it's not easy because the build scripts assume scothc's .sos and .hs files live in the same tree.
