Features that are missing in other structural analysis programs


The development, testing, sales and support of structural analysis software for structural design and FEM by Dlubal Software are 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 programs include a wide range of useful features that may be missing in similar structural analysis programs. Some of them are listed here. Therefore, RFEM and RSTAB are not only a good alternative to other structural analysis software such as SAP 2000, STAAD Pro, RISA, Robot Structural Analysis, SCIA Engineer, SOFiSTiK etc., but they are often the first choice for structural engineers.
