Validating CFD simulations with experimental data enhances accuracy by comparing simulation outcomes with real-world conditions. This process identifies discrepancies, allowing adjustments to enhance model reliability. Ultimately, it builds confidence in the simulation's ability to predict wind load scenarios.
Creating a validation example for Computational Fluid Dynamics (CFD) is a critical step in ensuring the accuracy and reliability of simulation results. This process involves comparing the outcomes of CFD simulations with experimental or analytical data from real-world scenarios. The objective is to establish that the CFD model can faithfully replicate the physical phenomena it is intended to simulate.
Wind direction plays a crucial role in shaping the outcomes of Computational Fluid Dynamics (CFD) simulations and the structural design of buildings and infrastructures. It is a determining factor in assessing how wind forces interact with structures, influencing the distribution of wind pressures, and consequently, the structural responses.
Compliance with building codes, such as Eurocode, is essential to ensure the safety, structural integrity, and sustainability of buildings and structures. Computational Fluid Dynamics (CFD) plays a vital role in this process by simulating fluid behavior, optimizing designs, and helping architects and engineers meet Eurocode requirements related to wind load analysis, natural ventilation, fire safety, and energy efficiency. By integrating CFD into the design process, professionals can create safer, more efficient, and compliant buildings that meet the highest standards of construction and design in Europe.
In RWIND Simulation, it is possible to divide the model in different zones. This allows for different surface roughness to be assigned to the zones. In addition, local results can be better evaluated.

The RWIND Simulation program for generating wind loads based on CFD can be utilized in different languages; for example, in:
- German
- English
- Czech
- Spanish
- French
- Italian
- Polish
- Portuguese

Utilize the RWIND Simulation program to consider a surface roughness of the model surface by applying a modified wall boundary condition. The numerical model is based on the assumption that grains with a certain diameter are arranged homogeneously on the model surface, similar to sandpaper. The grain diameter is described with the parameter Ks and the distribution with the parameter Cs. By considering the wall roughness, the numerical flow simulation can capture reality more closely.
The volume space in RWIND Simulation can optionally be discretized with the second-order theory between the cells.
This extended approach usually results in more accurate results despite poorer convergence behavior.
Computational Fluid Dynamics (CFD) is a powerful tool in modern engineering practice. However, as with all simulation methods, the question arises: how reliable are the results?
What is the difference between the RANS, URANS, and DDES turbulence models?
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?
How can I consider various wind profiles for various wind directions?
Is it possible to use load transfer surfaces in RFEM 6 for wind load generation using RWIND?
