MOST in all directions for immersed forcing

Open hgopalan opened this issue 9 months ago • 3 comments

The immersed forcing assumes a continuous distribution of the terrain. This does not work well when we have an extreme case: two mountains with a river in-between or any other cases where the terrain drops to zero for a large region. This draft PR enhances the drag force calculations to account for this scenario and also to be able to include buildings in AMR-Wind simulations.

Please check the type of change introduced:

  • [ ] Bugfix
  • [X ] Feature
  • [ ] Code style update (formatting, renaming)
  • [ ] Refactoring (no functional changes, no api changes)
  • [ ] Build related changes
  • [ ] Documentation content changes
  • [ ] Other (please describe):

The end goal is to make the capability available to study loading on complex static structures not fixed to the ground and In ERF for urban microclimate simulations.

No regression or unit tests required as the existing ones for immersed forcing works with this method too. No changes in the input files are required either.
