A finite element model that uses h-adaptation is used to predict atmospheric wind fields and pollutant transport over the Nevada Test Site. Meteorological data are used to generate a diagnostic flow field; prognostic (forecast) solutions of the time-dependent equations of atmospheric motion and species transport are then obtained. Mass lumping, reduced integration and Petrov–Galerkin weighting are employed in the algorithm. A coarse mesh is first generated; the mesh is then refined and unrefined utilizing parameters based on velocity and species concentration gradients. The model runs on SGI workstations; a parallel version has been ported to the SGI Origin 2000 located within the NSCEE at UNLV.
