Scalability Issues For Wind Simulation Using Openfoam

The use of the OpenFOAM software for wind simulation over rugged terrain is studied in the paper. OpenFOAM requirements for runtime, virtual memory and disk space are considered using small and medium resolution Digital Elevation Models (DEM) models for single-process and multi-process cases when running on local workstation and small parallel systems. Based on obtained data, extrapolation of requirements for relatively high resolution models are made and issues concerning the scalability are discussed.
