The structural FEA software RFEM for analysis and design of plates, walls, shells, solids, and frame structures is a powerful program for various tasks of modern civil engineering. This program forms the basis of a modular software system: RFEM determines internal forces, deformations, and support reactions of general plate structures with or without member and solid elements.
The program version RFEM 5 provides a wide range of useful features and options for efficient and user-friendly work on your structural analysis projects.

System Requirements.
In order to use RFEM, the following system requirements should be met:
- Operating system Windows 7/8.1/10 64-bit
- x86 CPU with 2 GHz
- 2 GB RAM
- USB interface for the installation (if no installation via )
- 20 GB hard disk capacity, including approximately 4 GB required for the installation
- Graphics card with OpenGL acceleration and resolution of 1024 x 768 pixels. Onboard solutions and shared-memory technologies are not recommended
RFEM is not supported by Windows 95/98/Me/NT/2000/XP/Vista, Linux, Mac OS, or serveroperating systems.
Except for the operating system, there are no product recommendations, since RFEM basically runs onall systems that meet the aforementioned system requirements.If you use RFEM for intensive
calculations, the principle"themore thebetter"applies.Calculations of complex structural systems have to process huge amounts of data.Once the mainmemory is no longer sufficient, the hard drive is used for processing the data,which may significantlyslow down your computer.Therefore, a main memory upgrade usually speeds up calculation morethan a faster processor.
Since the RFEM computation kernel supports several processor cores, you can completely use thepotential of the 64-bit operating system.If your computer has sufficient RAM memory, you can use thefast and direct matrix solver method even for large models.
For a calculation of complex structural systems, we recommend the following configuration:
- Quad-core processor
- 8 GB RAM
