I have created a flexible beam in SimMechanics by superimposing the flexibility onto a rigid body, as described in some of the examples. The response is the same between the theoretical beam and the beam in SImMechanics. I would however like to join 2 beams together with a weld. I assumed the response would be the same as the response from the derived beam with two elements, but this is not the case.
Why is this? I am obviously doing something wrong. Any help will be appreciated.
