New Features and Tools for Efficient Work

Really Great Software

"I take this opportunity to thank you and your team for a really great software. After so many years of utilizing your software, we still see every day what your product is able to do and we really enjoy the application!

We look forward to more years together!"

At Dlubal, we focus on further development and improvement. In RFEM 6, numerous new features have been implemented, which make your daily work with the FEA program easier and more efficient. On this page, we present a selection of new features.

1

Import of Construction Site for Load Determination

Always keep an eye on the natural conditions of your construction site by defining it on a digital map. The address data (including the altitude) as well as the snow load zone, wind zone, and seismic zone are imported automatically. The load wizard also uses this data.
The map is also displayed with the construction site marked in the "Model Parameters" tab.

2

Integration of All Add-ons

Discover the advantages of working with the various add-ons for RFEM 6 and RSTAB 9. All add-ons are integrated in the programs. This allows seamless interaction between the individual program parts and ensure that your analysis and design runs smoothly. Examples for this is the determination of the ideal overturning moment of timber beams using the "Torsional Warping (7 DOF)" add-on or the consideration of staggered form-finding processes by means of the "Construction Stages Analysis (CSA)" add-on, and so on.

3

Output of Design Check Formulas

With Dlubal software, you always have an overview, regardless of whether your projects are in the reinforced concrete, steel, wood, aluminum, etc. industry. The program provides a detailed and clear overview of the design formulas used in your design (including reference to the equation used from the standard). You can also display these design formulas in the printout report.
4

Member and Member Set Representatives

Make your work easier with bars. For members and sets of members with identical properties, you can define representatives for the model organization, design, and documentation.
The results of these representatives can easily be shown in the result tables.

5

Unit Stresses of Sections

Make sure nothing collapses on you: To estimate the resistance of member cross-sections, it is possible to display the unit stresses for the unit loads N = 1 kiP, My = 1 kiP/ft, and so on, when selecting the cross-sections.

6

Load Transfer Surface

Keep an eye on all surfaces. The surface with the "Load Distribution" stiffness type has no structural effect. You can use it to consider the loads from surfaces that have not been modeled, for example, facade structures, glass surfaces, trapezoidal roof sections, and so on.

7

Surface Contact

Make your work easier. A surface contact serves to describe a contact definition between two or more surfaces that are at a distance from each other It is no longer necessary to create a contact solid between the surfaces.

8

Rigid Link

This feature helps you with links. You can easily define rigid links between two lines or surface edges.


9

Imperfection Cases

The organization of imperfections is efficiently solved by imperfection cases. The cases allow you to describe an imperfection from local imperfections, equivalent loads, initial sway via table (new), a static deformation, a buckling mode, a dynamic mode shape, or a combination of all these types (new).

10

Design Situations

Use design situations to support your design checks. They allow you to collect the relevant load situations for design For example, you can define a design situation for the design of different materials.

11

Extension of Snow and Wind Load Wizards

Discover the new functions of the snow and wind load wizards:

  • Loading of hybrid models made of members and surfaces (RFEM only)
  • Connection to the Geo-Zone Tool (depending on the global construction site definition)
  • Switching off surface sides
12

Modern Online Licensing System

Dlubal Software supports its customers with their construction planning worldwide. Due to the modern online licensing system, the licenses of RFEM, RSTAB, and other programs can be distributed all over the world and assigned to the respective users via the Dlubal Account.

13

Script Manager

  • Interactive modification of chapters as well as creation of new user-defined chapters
  • Import of PDFs, formulas, 3D graphics, and so on
  • Output of the design check formulas used in the design (including a reference to the used equation from the standard)
  • Modern printout report design
15

Faster Calculation

Do you have to calculate many load combinations in your models? Then several solvers (one per core) are started in parallel, each of which calculates a load combination. This ensures a better utilization of the cores and thus a faster calculation.

16

Improved Result Diagram Window

Discover the new features in the result diagram window:

  • Parallel work in the result diagram window and in the model
  • Optional overlapping display of results (for example, several similar structural components in one image)

17

Webservice and API

Technology takes you further, also in your daily work with RFEM / RSTAB. The new API technology Webservice allows you to create your own desktop or web-based applications by controlling all objects included in RFEM 6 / RSTAB 9. Entire libraries and numerous functions are available to you. Thus, you can easily perform your own design checks, effective modeling of parametric structures, and optimization and automation processes using the programming languages Python and C#. Dlubal Software makes your work easier and more convenient. Convince yourself!

18

Extension of IFC Interface for Improved Open BIM Process

There are also improvements in the data exchange to make your work process easier. In addition to the import of IFC 2x3 (Coordination View & Structural Analysis View), the import and export of IFC 4 (Reference View & Structural Analysis View) is now supported.

19

Wind Simulation (RFEM or RSTAB Environment)

Discover the new features in RFEM and RSTAB for determining wind loads using RWIND:

  • Useful load wizards for generating wind load cases with different flow fields in different wind directions
  • Wind load cases with freely assignable analysis settings including a user-defined specification of the wind tunnel size and wind profile
  • Comprehensive display of the wind tunnel with input wind profile and turbulence intensity profile
  • Visualization and use of the RWIND simulation results
  • Global definition of a terrain (horizontal planes, inclined plane, table)
20

New Model Types

In RFEM, there are new useful result types available for you:

  • 2D | XZ | 3D
  • 2D | XY | 3D
  • 1D | X | 3D

These model types allow you the modeling in a 1D or 2D environment (with optional cross-section rotation in all directions), but also a three-dimensional load application and resulting 3D internal forces.



21

Definition of Hotkeys

Would you like to make your work process more efficient? Then use hotkeys for a variety of commands. This allows you to quickly and easily execute frequently used commands with a previously assigned keyboard shortcut.
Incidentally, this also works with your computer mouse. If this has other keys in addition to the right, left and middle keys, you can also use these for a hotkey.

22

Assigning Loads to New Load Case

Do you work with loads? Then this feature is helpful for your work! For member loads, surface loads, etc., you can subsequently move loads to another load case.
23

Mass Loads
