In addition to our technical support (e.g. via chat), you’ll find resources on our website that may help you with your design using Dlubal Software.
Frequently Asked Questions (FAQ)
Customer Support 24/7
AnswerIt is possible because RFEM provides the perfect basis for the calculation and design of piping systems. The RF-PIPING and RF-PIPING Design add-on modules provide support for modeling and design.
Since support structures and other components of the entire model can also be represented, a realistic analysis and design is possible.
Main Programs of RFEMThe RFEM basic programs are used to define structures, materials, and actions.
Modeling of pipelines including typical fittings such as valves, flanges or reducers.
- RF-PIPING Design
Comparison of existing and allowable stresses of piping systems
- EN 13480-3
- ASME B31.1
- ASME B31.3
Dynamic AnalysisIf earthquake calculations or vibration analyzes are necessary on the building, the RF-/DYNAM Pro add-on modules provide suitable tools for determining natural frequencies and shapes, analysis of forced vibrations, for generating equivalent loads, or for nonlinear time history analysis.If you have any further questions on the Dlubal programs, please do not hesitate to contact the sales department.
AnswerThe files from AutoCAD Plant 3D can be transferred to RFEM by using the CAD/BIM model feature. There are the formats STEP (*.stp, *.step), IGES (*.igs, *.iges), or *ifc available; the model is loaded as a base to create the pipe in RF‑PIPING Design.
AnswerThe operational combinations are not intentionally transferred into the add-on module because there is no requirement in the standard to evaluate them. You can see the internal forces or the responses induced by these combinations directly in RFEM.
The easiest way to find the internal forces at these nodes is to print the pictures of members into the printout report.
If this solution is not an option, you can also find the values in the result table 4.1 in the printout report. Since the extreme values are only activated by default, it is still necessary to activate nodal values in the selection.
It is usually not reasonable to include the internal forces of all member in the printout report. Therefore, you can only select the members that are relevant to you.

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.
“Thank you for the valuable information.
I would like to pay a compliment to your support team. I am always impressed how quickly and professionally the questions are answered. I have used a lot of software with a support contract in the field of structural analysis, but your support is by far the best. ”
