New Programs for Cold-Formed Sections

SHAPE-THIN 9 | RF-/STEEL Cold-Formed Sections

The SHAPE‑THIN 9 stand-alone program and the RF‑/STEEL Cold‑Formed Sections add-on module allow you to design general cold-formed sections.

New Program: RWIND Simulation

Wind Simulation (Digital Wind Tunnel) & Wind Load Generation for RFEM or RSTAB

RWIND Simulation is a stand-alone program for numerical simulations of wind flow around structures of any shape.



Structural FEA engineering software RFEM allows easy and effective modeling as well as structural analysis and design of general 2D and 3D structures consisting of member, plate, wall, shell, solid, and contact elements.



Structural frame analysis software RSTAB contains a similar range of functions as RFEM, with special attention to beam, frame, or truss structures. Therefore, it is very easy to use and for many years it has been the best choice for structural frame analysis.

For Students

Structural Analysis Software for Students for Free

Dlubal Software supports students by providing them with the structural analysis software for free during their studies at a university, college, or institute of technology. Many students have already seized the opportunity to benefit from this support.

  • "Good tool, half the job": This proverb also applies to the software industry. The better a program is tailored to a task, the more effectively it can be solved.

  • When modeling frameworks, RSTAB and RFEM offer various options for controlling the transfer of internal forces at the connection points of the members.

  • If a member is laterally supported due to a compressive axial force to prevent buckling, it must be ensured that the lateral support is actually able to prevent buckling.

  • A new building was built on the site of the old temporary station building of the railway station in Karlovy Vary, meeting the current requirements for the operation of station buildings. The design of the load-bearing steel structure was performed by the Dlubal customer KONSTAT s.r.o.
  • The large hall building is comprised of a steel arched roof. The arched hall includes a 72 ft x177 ft rectangular floor plan, 33 ft height and 66 ft roof radius.
