A Perfect Combination

RWIND 2 and RFEM 6 can now be used to calculate wind loads from experimentally measured wind pressures on surfaces. Basically, two interpolation methods are available to distribute pressures measured in isolated points across the surfaces. The desired pressure distribution can be achieved using the appropriate method and parameter settings.

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. This guide outlines the essential steps in developing a validation example for CFD simulation, from selecting a suitable physical scenario to analyzing and comparing the results. By meticulously following these steps, engineers and researchers can enhance the credibility of their CFD models, paving the way for their effective application in diverse fields such as aerodynamics, aerospace, and environmental studies.

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. Understanding the impact of wind direction is essential for developing designs that can withstand varying wind forces, ensuring the safety and durability of structures. Simplified, the wind direction helps in fine-tuning CFD simulations and guiding structural design principles for optimal performance and resilience against wind-induced effects.

You can display the RWIND results directly in the main program. In the Navigator - Results, select the Wind Simulation Analysis result type from the list above.

Currently, the following results are available, which refer to the RWIND computational mesh:

Do you already know the editor for mesh refinement control? It is a great help for your work! Why? It's easy – it gives you the following options:

• Graphic visualization of the areas with mesh refinements
• Mesh refinement of zones
• Deactivating the standard 3D solid mesh refinement with transversion into the corresponding manual 3D mesh refinements.

These options help you to formulate a suitable rule for meshing the entire model, even for the models with unusual dimensions. Use the editor to efficiently define small model details on large buildings or detailed meshing areas in the coating area of the model. You will be amazed!

The stand-alone program RWIND 2 takes care of fresh air. It is used for the numerical simulation of wind flow and is available in a Basic as well as a Pro version. What additional features does RWIND Pro offer you? It allows for the calculation of transient incompressible turbulent wind flows (in addition to the stationary ones in RWIND Basic). But that's not all. Intrested to learn more? Find out more here:
