Question:
I have two solids that are adjacent to each other, but not congruent. What should be considered in the modeling?
Answer:
Two solids adjacent to each other share a common boundary surface in the contact area. Away from it (that is, where no additional solid is adjacent), the boundary lines of the other connected surfaces are defined; see Image 01.
When modeling, it is necessary to divide the side surface of the larger solid.
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.
