What can I do to increase the performance in the case of a very large model?

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 useful 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/RSTAB files as possible opened at the same time,
  • upgrade your PC. For example, you can often achieve a 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 is a lot of them in the model, it may sometimes be useful to disconnect them (see Figure 02). However, the big advantage of adjusting the loads automatically in the case of any changes in the model will be lost.

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

A 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 always work with the current version of RFEM/RSTAB.
