What can I do to improve the performance of a very large model?


In order to optimize or minimize all processes in general for larger models, attention should be paid to various points. It can be an advantage if

  • the wireframe model is used instead of the filled model in the graphic
  • displaying of the tables and navigator are deactivated,
  • our programs are added to the exceptions in the settings of the antivirus program,
  • as few applications and RSTAB/RFEM files as possible are opened at the same time,
  • the PC is upgraded. For example, you can often achieve a significant increase in performance with SSD memory. The PC should also have sufficient random access memory.
Furthermore, generated loads can 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 separate them (see Figure 2). However, the enormous advantage that the loads are adjusted automatically when changes occur in the model will be lost.

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

It may also be caused by missing user rights if the program reacts slowly. If you are not working using an administrator account, the user must have full access rights to different directories and subdirectories.

Furthermore, you should pay attention to always work with the current version of RSTAB/RFEM.
