Optimize RFEM 6 and RSTAB 9 Models

What can I do to increase the performance when the model is very large?


Answer:

Generally, in order to optimize or minimize the time required for all processes in the case of large models, you should pay attention to various points. It might be helpful to:

  • Use the wireframe model in the graphic instead of the solid model,
  • Deactivate the display of tables and the navigator,
  • Add our programs to the exceptions in the settings of your antivirus program,
  • Have as few applications and RFEM 6/RSTAB 9 files as possible open at the same time,
  • Upgrade your PC. For example, you can often achieve significant performance increase with an SSD memory. Your PC should also have sufficient RAM memory.

Furthermore, generated loads can also negatively affect the performance, as they are recalculated in the background after each work step. If there are many of them in the model, it can be useful sometimes to disconnect them (see Image 02). However, the big advantage of adjusting the loads automatically is if any changes are made to the model the loading will be adjusted automatically.

It may also be helpful to save the RFEM 6/RSTAB 9 files locally, instead of in a network.

One possible cause of the slower reactions of the program may be missing user rights. If you are not working with the administrator account, it is necessary to have full access rights to various directories and subdirectories.

Furthermore, you should ensure that you are always working with the current version of RFEM 6/RSTAB 9.
