Surface Side
Glossary Term
Since a surface is a 2D object whose thickness is considered a physical property, the results are displayed either on the positive or the negative side.
Orientation
The position of the positive or negative surface side can be controlled by the local axis system of the surface: the positive surface side is the side in which the positive z-axis runs. The negative surface side lies in the direction of the negative z‑axis. You can activate the axis system of the surface using the 'Display' navigator (see Figure 01).
Graphical Check
You can use the '+/- z-Surface Side' option to check the position of the surface sides (see Figure 02). It is important for the definition of foundations with failure or also for a reinforcement layout. The top side of a surface is shown in red, the bottom side in blue.

New
For relatively large or relatively small surfaces, it can happen that the automatically created result values do not fit the model: In case of large surfaces, there can be too much result values, in case of small surfaces, too few.

Increased Calculation Performance by Reducing the Nodal Degrees of Freedom
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).
- How can I display the results from RF‑PUNCH Pro exactly in the critical perimeter with a result value?
- When calculating an oblique plate, I obtain very high result values for the line supports at 2 edge nodes. Why is it so and how can I avoid it?
- In spite of having defined average regions, they are not considered in the design in RF‑CONCRETE Surfaces. What setting did I miss here?
- How are the signs to be interpreted for the release results of the line release and line hinges?
- Why is the deflection of the reinforced concrete floor sometimes greater when selecting a larger basic reinforcement?
- Is it possible to use a smooth region in the result from contact stress?
- I would like to calculate and design "temporary structures." What do I need for this?
- Which programs can I use to calculate and design power plants?
- Why do I get such a small amount of reinforcement for the upstand beam? The amount of reinforcement for the downstand beams is significantly larger.
- In the filter settings for the values on surfaces, you can display a certain range of results and hide the rest. How can I hide a certain range of values and display the rest?
