FEA Software RFEM 6 | Interfaces

Structural Analysis & Engineering Software

Dlubal Software should move you forward and not slow you down in your working process. Therefore, the FEA software RFEM has a large number of interfaces to different programs. Do you already know RFEM? It allows you to model as well as perform the structural and dynamic analysis and design of models with member, plate, wall, folded plate, shell, and solid elements:

Due to the modular software concept, you can enhance the main program RFEM with various add-ons and thus apply it in a wide variety of areas.

BIM-Oriented Planning

Helpful 3D Rendering in RFEM

“When extending the mosque in Mecca, it was especially helpful in RFEM to visualize the structure in 3D rendering and share the results with project partners from different cultural backgrounds.”

Project: Expansion of the Holy Mosque in Mecca, Saudi Arabia

A major advantage of RFEM is the interconnectability of the program. Dlubal Software provides various interfaces to other software by default. This allows you to easily exchange model data with CAD programs, for example, in order to make your work process more efficient.


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. Check it out now!


Integration in Autodesk Revit

Do you enjoy working with Autodesk Revit and wish there was an interface to the Dlubal Software? Then your wish has already become a reality! The direct bidirectional interface in RFEM 6 / RSTAB 9 to Autodesk Revit makes it easy for you: A structure created in RFEM/RSTAB can be visualized in Revit and prepared for the design engineer. In the same way, it is possible to calculate and design a Revit model in RFEM/RSTAB. You can even easily align the subsequent modifications in both the Revit and the RFEM/RSTAB model. Does that sound like a dream? Then live it and read more at:


RFEM 6 Interfaces to Rhino & Grasshopper

Rhinos are considered stubborn and inflexible. Rhino is clearly the exception. The bidirectional interface RFEM 6 - Rhino allows you to transfer various line types as well as surfaces (plane, rotated surface, and NURBS).

Also the bidirectional Grasshopper interface allows you to export and import model data, load cases and combinations, and the loads themselves. Instead of volatility, you will find a stable connection that you cannot build on, but that allows you to plan ahead.


SAF Interface

Dlubal Software has also interfaces with open source software, such as SAF. This will make your work much easier. RFEM 6 and RSTAB 9 support the data exchange using the Structural Analysis Format (SAF). The structural analysis programs offer you both import and export. SAF is based on MS Excel. It is a file format intended to facilitate the exchange of structural analysis models between different software applications. We can assure you: It is definitely an asset to any structural engineer.


Autodesk-AutoCAD Interface

Use the interfaces for more efficient work. You can import your structures in the DXF format as lines from Autodesk AutoCAD into RFEM 6 / RSTAB 9.

Furthermore, you can export different objects (for example, cross-sections) from RFEM 6 / RSTAB 9 to separate layers in Autodesk AutoCAD.


Microsoft Excel

MS Excel is a classic when it comes to the further processing or preparation of table values. We have implemented a direct link to Microsoft Excel for you in RFEM 6 / RSTAB 9. Thus, you can export the tables of RFEM 6 / RSTAB 9 individually or all at once, directly into an Excel spreadsheet. Furthermore, you can transfer the Excel tables to RFEM 6 / RSTAB 9. We are always working to offer you even more options in RFEM / RSTAB.


DXF Format (*.dxf)

You are certainly already familiar with the DXF format. The DXF file format provides you with the most common data exchange formats available in the CAD area. DXF files can be imported as well as exported with minimum effort.


IFC Interface in RFEM 6 / RSTAB 9

Dlubal software has many different interfaces. One of them is the IFC (Industry Foundation Classes) interface. This is divided into several areas, called "Views." Furthermore, there are various versions of the IFC format. Take a closer look here. Version 4.0 is supported for both import and export. However, the older version 2x3 is only supported for import. Regardless of in which direction you exchange the data, you can process the StructuralAnalysisView as well as the ReferenceView (Coordination View).

When importing the ReferenceView, the individual IFC objects can be converted into RFEM-native elements. You can also use the conversion tables to adapt the cross-section and material descriptions. The export in the ReferenceView allows you to display the structure in IFC viewers and CAD programs. On the other hand, StructuralAnalysisView allows you to transfer the structural model including loading. As you can see, there are numerous options available to you.


STEP Interface

You can import STEP files into RFEM 6. The data is directly converted into the native RFEM model data.

The STEP format represents a standard interface initiated by ISO (ISO 10303). In the geometry description, all shapes relevant for RFEM (line, surface, and solid models) can be integrated by the CAD data models.

Note: This format is not to be confused with DSTV interfaces, which also use the file extension *.stp.


Background Layers

To simplify your modeling, use background layers stored in the work window of RFEM 6 / RSTAB 9 for the input of graphical object. These layers are generated from an imported DXF file. Read more about this:
