Rfem - 5 Manual
The manual introduces the concept of FE Mesh Refinement . Most users use "Global Refinement" (smaller elements everywhere). This is computationally stupid.
The RFEM 5 manual is brutally honest here: "An automatic mesh generation is not a substitute for engineering judgment." rfem 5 manual
But six months later, you encountered the problem . A hyperstatic shell structure wasn't converging. A buckling analysis gave you a mode shape that made no physical sense. Or worse, the results looked perfect, but the reactions were off by 40%. The manual introduces the concept of FE Mesh Refinement
The manual’s section on (Chapter 7.2) is a masterclass in boundary conditions. Buried in the footnotes is the explanation of Spring Constants . The RFEM 5 manual is brutally honest here:
Tonight, open your digital PDF of the RFEM 5 manual. Search for "singularity." Read every result. Then check your last three projects. You will likely find at least one hidden error.
