What flow model and type of analysis is used in RWIND Simulation?


RWIND Simulation uses a numerical CFD (Computational Fluid Dynamics) model to determine the airflow around objects using a digital wind tunnel.

RWIND Simulation is designed to use a variety of numerical solvers. We currently recommend the OpenFOAM ® software package, which showed very good results in our tests and is also a widely used tool for the CFD simulations.

The numerical solver is called "RWINDSimulationSolver" and belongs to the SIMPLE solver family. It is a solution for incompressible turbulent flow at steady state by using the SIMPLE (Semi-Implicit Method for Pressure Linked Equations) algorithms.
