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.
-
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.
-
Display of Topology on Deformed Structure
With the activated option "Topology on form-finding shape" in the Project Navigator - Display, the model display is optimized based on the form-finding geometry. For example, the loads are displayed in relation to the deformed system.
-
Automatic Preliminary Form-Finding of Membrane Surfaces
Activating the "Show Preliminary Form-Finding" option in the shortcut menu leads to an automatic preliminary form-finding according to the saved form-finding properties when you change the structure of membrane surfaces. This interactive graphics mode is based on the force density method.
-
Updating the Revit Model
The direct interface with Revit allows you to update the Revit model according to the changes you have made in RFEM or RSTAB. Depending on the modification, the Revit objects may have to be regenerated (deleting the object and subsequent regeneration). The regeneration is performed on the basis of the RFEM/RSTAB model.
If you want to avoid this regeneration, activate the option "Update only materials, thicknesses, and sections." In this case, only the properties of the objects will be adjusted. Changes different from those in material, surface thickness, and section are, however, not considered in this case.
-
Eccentricity of Member Loads
For member loads of the load type "Force", you can define eccentricities. You can apply the load eccentricities by means of an absolute or relative offset.
It is recommended to use the large deformation analysis to consider all effects of eccentric loads.
-
Considering the Stiffness of Gas Solids in Nonlinear Time History Analysis
The stiffness of gas given by the ideal gas law pV = nRT can be considered in the nonlinear dynamic analysis.
The calculation of gas is available for accelerograms and time diagrams for both the explicit analysis and the nonlinear implicit Newmark analysis. To determine the gas behaviour correctly, at least two FE layers for gas solids should be defined.

Display of Forces and Deformations of Hinges and Releases
RFEM offers the following tables to display forces and deformations of hinges and releases:
- 4.45 Line Hinges - Deformations
- 4.46 Line Hinges - Forces
- 4.47 Member Hinges - Deformations
- 4.48 Member Hinges - Forces
- 4.49 Nodal Releases - Deformations
- 4.50 Nodal Releases - Forces
- 4.51 Line Releases - Deformations
- 4.52 Line Releases - Forces
The tables can be displayed in the prinout report. Moreover, the results in line hinges and line releases can be displayed graphically. It can be controlled by the Project Navigator - Results.
-
Bar Reinforcement Export to Revit
The reinforcement proposal from RF-/CONCRETE Members can be exported to Revit. The rectangular and circular cross-sections are currently supported.
The reinforcement bars can be modified retroactively in Revit.
-
Imposed Line Deformation
Imposed line deformations can be defined for supported lines in RFEM. For example, foundation settlements can be simulated with this function.
Moreover, it is possible to define imposed rotations for lines.
