I am quite new on Karamba. I was trying to model a sandwich beam.
I have created a top and bottom beam element, and to simulate the core, I have made a shell element with the same thickness of the base of my beam.
My model seems to work fine, I don’t get any error. But the result in the displacement differs by 16% with my analytical calculations. I have also tried to make a model with another FEM software, and the result confirms that the analytical calculations are fine, while the Karamba model is not.
What is wrong in the Karamba model? I guess I am missing something…
