Terrain Modeling #1015

Closed hgopalan closed 1 month ago

hgopalan commented 2 months ago

This draft PR defines a framework for incorporation of Terrain effects within the AMR-Wind solver. The work flow is divided into three parts:

  1. A preprocessing module to read the terrain details and create the blanking and drag information.
  2. A module to compute the forcing term to account for the presence of the terrain.
  3. A sponge layer to enhance the outflow boundary conditions.

The force terms can be modified to include Trees/forested areas and one-way coupling with waves without including a more comprehensive two-phase flow.

Initial testing of the model for WFIP2, Perdigao, and few other sites show that the runs are stable. The results from the simulations will be compared with existing measurements and updated in the few months to include possible modifications.

Looking for suggestions and comments.
