This manual presents selected topics relevant to the analysis with the RFEM software. They cover important aspects of the calculation and the approach of finite elements used in the FEA program.
In the Calculation chapter, topics concerning nonlinear behavior, parallelization, and types of analyses are discussed.
The Finite Elements chapter introduces finite elements from the topological point of view, presents the types of finite elements as well as their integration procedure, and explains the mesh settings and possibilities to prevent zero-energy modes.
