Dlubal RFEM 6
Pricing. You can try it free before you buy. Paid plans start at $798 a month. See full pricing · Updated October 3, 2026
Dlubal RFEM 6 is a Windows finite element program for structural engineers that models members, plates, shells, and solids, and can exchange an analytical model through IFC plus Revit and Tekla add-ins.
Structural engineers use RFEM 6 when the model is more than a stick frame. The main program defines plates, walls, shells, members, and solids, then calculates deformations, internal forces, support forces, and soil contact stresses. Design checks for concrete, steel, and timber sit in add-ons, so the main-program price on the product page is not a full design suite.
The same page's price calculator separates how you pay: US$5,320 to buy the main program, US$798 for 1 month, US$1,596 for 3 months, US$2,394 for 6 months, and US$2,926 for a 12-month subscription. Those figures are the main program only, in US dollars, before any service contract.
A service contract is optional and billed per year. On the same calculator, Basic adds US$900 for the first main-program license and Pro adds US$1,340. If Basic stays selected, the buy total shown is US$6,220, not US$5,320. The product page also offers a free 90-day full version.
IFC 4.0 can be imported and exported. IFC 2x3 can be imported, and Dlubal's FAQ says that older schema is not an export option. Revit and Tekla links are add-ins you install yourself from the RFEM tools folder, and they need the WebService option turned on. The programs run on 64-bit Windows 10 and Windows 11.

Frequently asked questions
How much does Dlubal RFEM 6 cost?
On the RFEM 6 product page calculator, the main program is US$5,320 to buy, US$798 to rent for 1 month, US$1,596 for 3 months, US$2,394 for 6 months, and US$2,926 for a 12-month subscription. These amounts are the main program alone. Design add-ons are priced separately in the webshop, and a selected service contract is added on top.
What is the RFEM 6 service contract, and is it required?
It is optional. The same calculator adds US$900 per year for Service Contract Basic on the first main-program license, or US$1,340 per year for Pro, and with Basic left selected a buy shows US$6,220 rather than US$5,320. Clear the service-contract field if you want the main-program price on its own. Extra-license rates are lower and are listed in Dlubal's service contract terms, so confirm those before buying a second seat.
Is there a free RFEM 6 trial?
Yes. The product page offers a free full version for 90 days. That is the trial listed here, not a reduced viewer. Download terms can still change, so start it from dlubal.com rather than from an old installer.
Does RFEM 6 run on Mac?
No. Dlubal's operating-system FAQ lists RFEM 6 on 64-bit Windows 10 and 64-bit Windows 11. Mac and Linux are not listed. The Revit and Tekla add-ins are Windows installs as well, placed under the RFEM program files.
Does RFEM 6 open IFC and Revit files?
IFC 4.0 can be imported and exported, while IFC 2x3 can be imported only, according to Dlubal FAQ 005373, in either the Structural Analysis View or the Reference View. Revit is not opened as an RVT file inside RFEM. A separate add-in, installed by hand, supports Revit 2021 through 2027 and needs the WebService server started in RFEM options.
How does RFEM 6 compare with a BIM modeler?
RFEM 6 is an analysis program, not the place where an architect authors the building model. Revit and Tekla stay the authoring tools, and Dlubal connects to them with add-ins you install from the RFEM tools folder. Tekla Structures 2021 through 2026 are the versions named in the Tekla FAQ. IFC is the file path when you are not using those add-ins.
Who is RFEM 6 for?
Dlubal describes it for structural and civil engineers working on member, plate, shell, and solid models. The product page says the program family has more than 130,000 users and that standards cover reinforced concrete, steel, and timber once the matching add-on is licensed. A 90-day full trial is the way to test the main program before paying.
