The following manual deals with selected topics in RFEM. The aspects of a calculation and finite elements in RFEM are covered.
The Calculation chapter includes the explanation of nonlinearity, parallelization, types of analysis, static analysis and dynamic analysis.
The Finite Elements chapter introduces finite elements from the topological point of view, presents a list of all elements, as well as their integration procedure, discusses and explains mesh settings and possibilities of preventing zero-energy modes.
