There can be many reasons for this. Please send us the "authorization.txt" file, which you can create in RFEM/RSTAB using the program menu "Help → Authorization → Diagnostics". This is also possible in the demo version.
If you have changed your computer or formatted your hard drive without changing the partitions, please contact our hotline. You will then receive your existing license file with instructions for reactivating the softlock.

The material database in RFEM, RSTAB and SHAPE-THIN contains steels according to the Australian standard AS/NZS 4600:2005.
Use the "Independent mesh preferred" option in the FE mesh settings to create an independent FE mesh for the integrated objects. This allows you to generate a significantly more detailed and precise FE mesh for individual objects that are integrated into one another.
In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
In RFEM 6 and RSTAB 9, you have the option to enter "Visual Objects" as guide objects. You can import the file formats 3ds, stl, and obj.
These objects allow you to create a better reference to the dimensions.
