RWIND 2 | Calculation
RWIND Basic uses a numerical CFD model (Computational Fluid Dynamics) to simulate wind flows around your objects using a digital wind tunnel. The simulation process determines specific wind loads acting on your model surfaces from the flow result around the model.
A 3D volume mesh is responsible for the simulation itself. For this, RWIND Basic performs an automatic meshing on the basis of freely definable control parameters. For the calculation of wind flows, RWIND Basic provides you with a stationary solve and RWIND Pro provides a transient solver for incompressible turbulent flows. Surface pressures resulting from the flow results are extrapolated onto the model for each time step.
Recommended Wind Tunnel Size Compatible With Eurocode (EN 1991-1-4)
The size of the computational domain (wind tunnel size) is an important aspect on wind simulation that has a significant impact on the accuracy as well as the cost of CFD simulations.
- Is there an option to export the results of drag forces of all zones from RWIND in a table?
- When exporting my model from RFEM to RWIND, I get the message "Warning No. 7731 | Reading of logger file failed." What can I do to start the simulation in RWIND?
- What is the difference between RWIND 2 Basic vs. Pro?
RWIND 2 is a program (digital wind tunnel) for the numerical simulation of wind flows around any building geometries with determination of the wind loads on their surfaces. It can be used as a stand-alone application or used together with RFEM and RSTAB for complete structural analysis and design.
