Features Missing in Other Structural Analysis Programs


Certified acc. DIN EN ISO 9001

Development, testing, sale, and support of Dlubal Software is certified for the management system according to DIN EN ISO 9001.

Beyond Expectation

“After using about four other major analysis programs, I am extremely pleased by the subtle features of RFEM for its flexibility in modeling, interoperability, ease of analysis, error reporting and also in interpreting the results.

Added to this is the excellent support that is beyond expectation.”

Dlubal Software contains a wide range of useful features that may be missing in other structural analysis programs. Some of them are listed below. For this reason, RFEM and RSTAB are not only good alternatives to the programs such as SAP 2000, STAAD Pro, RISA, Robot Structural Analysis, SCIA Engineer, SOFiSTiK, and so on, but are often the first choice for structural engineers.
