Are there any model limits regarding the file size? May the file size (with FE mesh, results, and printout report) be greater than 4 GB?


There is no liimit of the program file size if you are using the 64‑bit system and the 64‑bit version of RFEM 5 or RSTAB 8.

The "Limit" is determined by the computer configuration.

It may happen that the available RAM memory plus the virtual memory defined in Windows (free memory space) is insufficient. In this case, you can optimize the computer configuration (more RAM, more free hard disk capacity).
