You can calculate the rotational restraint manually or using a program. Then, enter the resulting value in the "Settings" table as stiffness CD (see the image). To do this, set the type of rotational restraint to "Define Manually".

The material database in RFEM, RSTAB and SHAPE-THIN contains steels according to the Australian standard AS/NZS 4600:2005.
For design objects, you can optionally display sags or extreme results.
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).
