Creation and validation of a uniform beam model

[flisae]

Hello,

I am trying to define a model on the basis of the "generate_uniform_beam" method. To validate the model, I decided to perform a modal analysis on the beam but I can't obtain the same results as my FEM's results. I guess this difference could comes from a bad description of the geometry (mass_iner, I, pos_CG...) or the stiffness (EA, GAy, GAz...) with respect to the B FoR. My current model is a beam with square section (side =0.2 m ; length = 1.5m).

Thanks in advance !

Hi Florian,
I've just uploaded an example of modal solution for a problem with known answer in SHARPy cases. Please have a look.
