Summary0003056: FEM, 1D beam analysis example for Start WB and wrong results for 1D beam
DescriptionThe start wb only has FEM 3D and 2D analysis example of CalculiX cantilever. This is because the 1D example gives results an engineer would not expect. At the moment no example is added but the 1D beams are still supported.

I opened the bug report to have a reference. I have been in contact with the developer of CalculiX, the FEM solver we use. There seems to be some mathematical reasons for the problem.
