Increased Calculation Performance by Reducing the Nodal Degrees of Freedom
Product Feature
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 (e.g. trusses and membrane structures).

Simplified Blast Design According to AISC Steel Design Guide 26
Blast loads from high energy explosives, either accidental or intentional, are rare but may be a structural design requirement.

Depending on stiffness, mass, and damping, structures react differently to wind action.
- A single-span beam consisting of several apparently straight members receives small torsional moments in the load case of "dead load." Why?
- Does the program check the lap length of the vertical stirrups of a block foundation with smooth bucket sides?
- Why do I get a discontinuous area in the distribution of internal forces? In the area of the supported line, the shear force VEd shows a jump, which does not seems to be plausible.
-
When creating a new member, the existing member is divided into two members, or when adding a node on a member, a new perpendicular member is created.
Is there any option to prevent the members from being divided automatically? - Is there a possibility in RFEM to define a global polar grid whose origin lies, for example, in the global zero point and which applies to several surfaces?
- When comparing RF‑CONCRETE Columns with another design software, I get different results. How to explain the differences?
- The tables (or navigator) are not displayed despite activating the table window (or navigator). How to make them visible again?
- Why are certain model generators only displayed inactive/grayed out?
- I have problems with my printout report. The font is very large. In some cases, the columns overlap and the font is no longer legible.
- How is it possible to make factorized combinations of a dead load in the context of form‑finding?
