    In RFEM, it is possible to open and further edit structures with loads and load cases, which has been modeled in RSTAB. This may be necessary, for example, if it is determined during the model input that it makes sense to include surface elements such as wall panes in the existing RSTAB model.

    In order to open an RSTAB file in RFEM, you have to change the file type in the "Open" dialog box either to "File type RSTAB" or to "All Files." In this way, you can display not only the RFEM files, but also all RSTAB files stored in the selected directory. After opening the RSTAB file, you can save the model as an RFEM file for further editing.

    However, it should be noted that the printout reports or input data already created in add-on modules cannot be transferred.

    An RFEM file can be imported in RSTAB by renaming the file extension *.rf5 to *.rs8. Also in this case, all module entries and printout reports are deleted. You should also note that beam structures are only transferred in RSTAB; surface elements are deleted. 

  • Answer

    RSTAB is a 3D structural frame analysis program where the design of 2D and 3D frameworks is possible. The efficient RSTAB solver allows for linear and nonlinear calculations of internal forces, deformations, and support reactions.

    With RFEM, you extend the member design by plates, shells and solids according to the Finite Element Method. These elements can be combined arbitrarily in a structure. RFEM contains almost all functions from RSTAB; that is why also pure frameworks can be designed with it.

    The user interface and the handling of RSTAB and RFEM are almost identical, but RFEM offers more functions due to the greater scope of the program. The import of structure and load date from RSTAB to RFEM and vice versa is possible as long as the objects are supported by both programs.

    Various add-on modules are available for structural design in RSTAB and RFEM considering both material and standard-specific requirements. Thanks to the modular software concept, it is possible to put together a program package which is adapted to the individual needs. It is possible to upgrade the program at any time.
