Remarks

Stability model and additional forest canopy models under development.

The model uses some additional OpenFOAM-based tools:

- Structured mesher based on OpenFOAM's blockMesh: https://github.com/jonasIWES/terrainBlockMesher

- Additional tools to identify forest cells in the computational domain.
