RWIND Simulation
RWIND Simulation is a stand-alone program for numerical simulations of wind flow (digital wind tunnel) around buildings or any other objects and generating wind loads, i.e. forces acting on these objects.
This program was developed in cooperation among CFD SUPPORT, PC-Progress, and Dlubal Software GmbH. RWIND Simulation can be used as a stand-alone application or as a complement to Dlubal’s programs for static and dynamic analysis.
RWIND Simulation uses a numerical CFD model (Computational Fluid Dynamics) to perform wind flows around objects using a digital wind tunnel.
A 3D solid mesh is used for the simulation. RWIND Simulation carries out an automatic meshing where it is possible to set the entire mesh density as well as the local mesh refinement on the model very easily using a few parameters. A numerical solver for incompressible turbulent flows is used to calculate the wind flows and the surface pressures on the model. The results are then extrapolated on the model. RWIND Simulation has been designed to work with different numerical solvers.
We currently recommend using the OpenFOAM® software package, which has provided very good results in our tests and is also a frequently used tool for CFD simulations. Alternative numerical solvers are under development.
