Why Dlubal Software?
Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
-
Extended Display of Strains in RFEM
Display extended strains of members, surfaces and solids (e.g. important principal strains, equivalent total strains, etc.) 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.

Create 3D glTF Models (*.glb and *.glTF Formats)
RFEM and RSTAB models can be saved as 3D glTF models (*.glb and *.glTF formats). You can use a 3D viewer to view, rotate, etc. the models.
You can integrate the 3D glTF models into your own websites using JavaScript according to these instructions (as on the Dlubal website Models to Download).
-
Camera Fly Mode
With the view option Camera Fly Mode, you can fly through your RFEM and RSTAB structure. Control the direction and speed of the flight with your keyboard. Additionally, you can save the flight through your structure as a video.

Material Model Orthotropic Masonry 2D
The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.

SHAPE-THIN | Cold-Formed Sections
SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.
Read more about designing cold-formed sections with SHAPE-THIN and RF-/STEEL Cold-Formed Sections in this technical article: Design of a Thin-Walled, Cold-Formed C-Section According to EN 1993-1-3.
-
RF-/STEEL Cold-Formed Sections | Input
Since RF-/STEEL Cold-Formed Sections is fully integrated in RF-/STEEL EC3, the data is entered in the same way as for the usual design in this module. It is only necessary to select the design option for cold-formed cross-sections in the Details dialog box.
-
RF-/STEEL Cold-Formed Sections | Features
- Available for cold-formed L, Z, C, channel, top-hat, and CL sections from the cross-section database, as well as for cold-formed (non-perforated) SHAPE-THIN 9 cross-sections
- Determination of the effective cross-section considering the local buckling and the distortional buckling
- Cross-section ultimate limit state, stability, and serviceability limit state designs according to EN 1993‑1‑3
- Design of local transverse forces for webs without stiffening
- Available for all National Annexes included in RF-/STEEL EC3
- RF-/STEEL Warping Torsion module extension (license required) for stability analysis according to the second-order analysis as stress analysis including consideration of the 7th degree of freedom (warping)
-
RF-/STEEL Cold-Formed Sections | Results
The design results are displayed in RF-/STEEL EC3 in the usual way.
Among other results, the corresponding result windows include the effective cross-section properties due to axial force N, bending moment My, bending moment Mz, internal forces, and design summary.

CADS Footfall Analysis
Footfall Analysis links with RFEM, using its model geometry, so that the user is not required to create a second model specifically for footfall analysis -
CADS Footfall Analysis
There is a known complexity of calculating footfall response on irregular floors or staircases of any type.
