Many users do their engineering calculations with RFEM and RSTAB. Quite often, they also work in the areas of materials and automotive engineering.
With RFEM, you can examine even very complex structures with many plates and solids. RFEM is also often used for the analysis of details and connections.
With RSTAB, you can analyze framework-like constructions in an easier and faster way.
