In RFEM 5, you can easily meet this condition with a Nodal Release. For this, you need to define a release with the desired release condition on the relevant node in the Nodal Release dialog box. The example shown in the figure corresponds to this with a shear force release with the property of being fixed and Vz being positive. For a lifting load, the result is a decoupling of both members.

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).
This section offers useful information about general structural analysis and design as well as Dlubal Software programs.
Infotainment
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.
