Question:
Should the elastic surface foundation of the contact stresses σ-z be relative to a global or a local coordinate system?
Answer:
Elastic surface foundations always refer to the local coordinate system of the surface.
You can display the local coordinate systems using the shortcut menu: right-click the surface, then select the "Local Axis Systems on/off" option.
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.

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.
