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.

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.
-
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.

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.
-
Member Type "Dashpot"
The member type "Dashpot" can be used for time history analyses in RFEM/RSTAB with the add-on modules RF-/DYNAM Pro - Forced Vibrations and RF-/DYNAM Pro - Nonlinear Time History. This linear viscous damping element considers forces dependent on velocity.
With regard to viscoelasticity, the member type "Dashpot" is similar to the Kelvin-Voigt model which consists of the damping element and an elastic spring (both connected in parallel).

Data Exchange with Advance Steel Using *.smlx Files
When exchanging data with Advance Steel using *.smlx files, the interface is automatically detected. This means that *.smlx files can be created even if no version of Advance Steel is installed.
-
Material Database with Steels According to the Australian Standard AS/NZS 4600:2005
The material database in RFEM, RSTAB and SHAPE-THIN contains steels according to the Australian standard AS/NZS 4600:2005. -
Link to TeamViewer in Help menu
By opening the Help menu of RFEM and RSTAB, it is possible to directly access the TeamViewer. Customers with a Service Contract Pro can thus benefit from an easy and quick online support via video conference.

Display Properties
It is possible to assign different colors to various objects of a structure in order to make the rendering display of the structure more clearly arranged.
The following categories are available: Materials, Cross‑Sections, Member Types, Member Hinges, Surface Types - Geometry, Surface Types - Stiffness, Surface Thickness, Solid Types, Surface Sides, and User‑Defined Visibilities and Effective Length Factors.
