The most common cause is a lack of user rights.
Open RFEM or RSTAB by right-clicking the icon. In the shortcut menu, select the "Run as Administrator" option. Then, load the authorization file again using the menu "Help → Authorization".Question
Although the current authorization file has been loaded, the program runs as a demo version.
Mr. Baumgärtel provides technical support for Dlubal Software customers.
The material database in RFEM, RSTAB and SHAPE-THIN contains steels according to the Australian standard AS/NZS 4600:2005.
The results of solid stresses can be displayed as colored 3D points in the finite elements.
The number of degrees of freedom in a node is no longer a global calculation parameter in RFEM (6 degrees of freedom for each mesh node in 3D models, 7 degrees of freedom for the warping torsion analysis). Thus, each node is generally considered with a different number of degrees of freedom, which leads to a variable number of equations in the calculation.
This modification speeds up the calculation, especially for models where a significant reduction of the system could be achieved (for example, trusses and membrane structures).
Display extended strains of members, surfaces, and solids (for example, the important principal strains, equivalent total strains, and so on) in the Project Navigator - Results in RFEM as well as in Table 4.0.
For example, you can display governing plastic strains when performing the plastic design of connections with surface elements.
