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.
If members aligned in space meet in a node, the local x- or y-axes of the members do not lie in one plane, since the local z-axes are aligned in the plane of gravity.
If you want to consider guide objects in the overall view (F8 key or double-click on the mouse wheel) or, for example, in a particular direction of the views, you can enable this option in the settings of the particular guide objects (guidelines, background layers, line grids).
RFEM and RSTAB provide various options for entering nodal loads. These implemented features allow the user to define the nodal loads in relation to different components in space.
Once you have determined the final tendon geometry in RF‑TENDON, exporting the model to a CAD program can be useful. For this purpose, the module includes the option to export the file in the .dxf file format. You can select the export function by right-clicking the workspace. After selecting the DXF format and the storage location, additional settings can be made.
In the Formula Editor environment, you can specify any parameters (lengths, force values, and so on) to control load and geometry data in the modeling.
An individual user‑defined workspace can increase your productivity and make your daily work easier. This is why many users take the opportunity to adjust the toolbars in RFEM and RSTAB and to create their own toolbars containing the most frequently used commands.
