First Steps with RFEM
Question
When starting RSTAB or RFEM, I get a message saying that the graphics chip does not support the OpenGL hardware acceleration. Unfortunately, the rendering in the programs is no longer as detailed, and the work is not quite as 'continuous'. Can I still use hardware acceleration?Answer
OpenGL technology is used for 3D rendering, which must be supported suitably by the operating system and the graphics card. Since not every graphics card manufacturer is at the same level of OpenGL technology, Microsoft's technology serves as a reference. We use the standard Windows OpenGL features.In RSTAB and RFEM, you can activate or deactivate the hardware acceleration (OpenGL) using the menu 'Options' → 'Program Options' in the 'Graphics' dialog tab (see Figure 02). In the same dialog, an improved smoothing (antialiasing) can be set to prevent the edge effect. These options are activated after restarting the program.
The mentioned options are very dependent on the used graphics card. For the work with RSTAB and RFEM, we recommend a graphics card that accelerates OpenGL functions in terms of hardware. This is the case with all current graphics cards. It is very important that the drivers of the graphics cards are always kept up to date.
We do not recommend graphics solutions that are integrated into the chipset or main processor (Intel HD xxxx, G xx, Q xx). Notebooks are often equipped with two graphics chips, a power-saving integrated into the processor Intel HD chip, and an additional more powerful graphics chip (for example, from NVIDIA or AMD). In this case, it should be ensured that RSTAB and RFEM use the powerful graphics chip. In the links below this FAQ, you will find further information on how this works in detail.

Parameterized Input with Access to Cells of Other Tables
With the parameterized input it is possible to access also cells of other RFEM or RSTAB tables. For example, you can link a load parameter to a model data parameter. The reference is created by the $ sign.

Structural Analysis Models for Download
Download numerous structural models (for example, RFEM, RSTAB, or RWIND files) to utilize them for training purposes or for your projects.
- Can I keep the results from RWIND Simulation when deleting the FE mesh if I only adjust materials or support conditions?
- How can I change the colors of the selection and preselection?
- Is it possible to make the generated member loads from area loads via plane to act eccentrically on the member cross-section?
- After the calculation in the RF‑/DYNAM Pro - Equivalent Loads add-on module, the size of my file has increased significantly. The performance has worsened enormously. What could be the reason for this?
- Why are my imperfections displayed graphically in different ways and can I adjust the display?
- What happens with the programs and add-on modules in the case of the timeout of a network license? And how can I increase the timeout?
- Why is it not possible to select a load case in the RF-/STEEL add-on module for design, although it is defined in RFEM/RSTAB?
- Does the load generation also work for curved members?
- What effects can renumbering elements have on the printout report and the add -on modules?
- In my model, some surfaces are displayed in gray, while others are displayed in white without a gray filling. The "solid transparent" display type is selected for the graphics. How can all surfaces be displayed in gray?
