Surfaces in general can have many different sizes and shapes – from simple planes, such as walls, slabs or plates, through single-curved cylinders, such as silos, to multiple-curved membrane structures.
For structural analysis, surfaces are generated in the centroidal axis. By defining the thickness and the material, they have their stiffness. Thus, it is possible to determine deformations and internal forces which can be then designed according to the material and standard.

The architectural requirements for railings are still very high and usually require a high degree of transparency.
Buildings made of cross-laminated timber (CLT), glued-laminated timber and OSB panels modeled with the RFEM program
The model is constructed by means of parameters for geometry and loads and regenerates when the parameters are changed.

If the check box "Number of load increments" is deactivated, the number of load increments will be determined automatically in RFEM to solve nonlinear tasks efficiently.
The used method is based on a heuristic algorithm.
Frequently Asked Questions (FAQ)
- Which Dlubal programs do I need to calculate membrane and textile structures?
- Does a user-defined layer composition in RF-LAMINATE need to be shared separately with other users along with the RFEM model file or is this information stored directly in the RFEM file?
- For the direction of internal forces, I have four options under the "Grouped" selection box to smooth the internal forces. Which grouping should I choose here?
- I have modeled two nodes on a surface in RFEM. The results do not show the displacement at these two nodes. How can I obtain it?
- Are the Dlubal Software programs suitable for the analysis and design of hydraulic steel structures?
- I would like to analyze cable and tensile structures. Is it possible to use RFEM or RSTAB for this?
- Which add-on modules and programs do I need for laminate and sandwich structures as well as cross-laminated timber (CLT)?
- I would like to use surface releases to model a bolt connection, which can only absorb compressive stresses from the support. Unfortunately, I cannot do this because my model is always unstable. Is there a model as a template?
- How do I display the nodal displacements graphically?
- Are silos/tanks possible to export from RFEM into Revit?
