Abstract: This document describes a three-dimensional, high resolution, computationally efficient, diagnostic model for flow over complex terrain using a mass consistent approach. The differences between the current model and similar approaches are (a) the lower boundary conditions and (b) an efficient numerical method. The model includes the effects of topography and small surface features such as forest areas and buildings on the overall flow. The numerical implementation takes advantage of a multigrid method that greatly improves the computation speed. The framework of the model and associated implementations are described here. Several preliminary test cases for the model are also given in this documentation.
