Software for Wind Simulation & Wind Load Generation on Structures
FEM Analysis and Design of Structures
The structural analysis program RFEM is the basis of a modular software system. The main program RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells and members. The program also allows you to create combined structures as well as model solid and contact elements.
Analysis & Design of Frame/Beam/Truss Structures
The structural frame analysis and design program RSTAB contains a similar range of functions as RFEM, with special attention to frameworks. Therefore, it is very easy to use and for many years it has been the best choice for structural analysis.
CFD Simulation of Wind Flows
RWIND Simulation is a program for numerical simulations of wind flows around buildings or any other objects and generating wind loads, i.e. forces acting on these objects.
Interfaces for Data Exchange
The structural analysis software provided by Dlubal can be seamlessly integrated into the Building Information Modeling (BIM) process. A variety of interfaces allows you to exchange data from digital building models with RFEM or RSTAB.

The following study compares the wind pressure on a tall building obtained by RWIND Simulation with the results published by Dagnew et al. at the 11th Americas Conference on Wind Engineering in June 2009.

RFEM and RSTAB have a special interface for exporting models (i.e. structures defined by members and surfaces) to RWIND Simulation. In this interface, the wind directions to be analyzed are defined by means of related angular positions about the vertical model axis, and the height-dependent wind and turbulence intensity profile is defined on the basis of a wind standard. Based on these specifications, you can create your own load cases for each angle setting by using fluid parameters, turbulence model properties, and iteration parameters that are all saved globally. These load cases can be extended from STL vector graphics by partial editing in the RWIND Simulation environment using terrain or environment models.
You can also run the program RWIND Simulation manually without the interface in RFEM and RSTAB. In this case, the structures and terrain environment in RWIND Simulation are directly modeled by importing STL and VTP files. The height-dependent wind load and other fluid-mechanical data can be defined directly in RWIND Simulation.
- How do I determine wind loads on structures of any shape?
- Which packages are available for the Geo-Zone Tool?
- I saw somewhere that it is possible to set the ground level for a model in RWIND (for example, for a model with a basement). Unfortunately, I cannot find where to set this.
- Is it possible to keep the results from RWIND Simulation when deleting the FE mesh if I only adjust materials or support conditions?
- How is the entry of the turbulence intensity related to the profile of the turbulence intensity in the RWIND Simulation program?
- Is there the ability to apply the adjusted wind tunnel dimensions in RWIND Simulation for all wind load cases instead of making the revision manually for each load case?
- What is the optimal wind tunnel size in RWIND Simulation?
- On the dlubal.com website, I found the option to display the results along a line, or the option to enter the points manually. Where can I find this result view?
- I have defined a wind profile for RWIND Simulation up to a height of 100 m. Is the wind profile dependent on the size of the wind tunnel?
- How can I delete the RWIND Simulation results in an RFEM or RSTAB model?
