The plausibility check is generally a way of roughly testing the plausibility of a value or result. Using this check, the entries or results are not necessarily verified for correctness, but obvious inconsistencies should be detected. Thus, you can check the "plausibility" of the entered model and load data in the program.
The plausibility checks can be opened in RFEM and RSTAB under the Plausibility Check entry in the Tools menu.
When a discrepancy is detected, a message appears with detailed information about the problem.
