Now, I've run the analysis including a displacement condition of -2.19 for kp4 at the first load step, keeping conditions at kp1 and kp3, and kp4 is behaving as I want, but now the problem is that I'm getting a force reaction different to zero for kp4 at the beginning of the second load step...
Thanks Drej for your answer.
Do you have any idea, how can I make then, that the second load step applies the displacement condition, starting from the deformed position after the first load step?
Or this is just not possible?
I'm performing a two load step analysis. In the first step I'm pre-loading the structure at two key points (points 1 and 3) by applying a displacement condition. In the second step, once the structure is preloaded, I'm actuating the structure from a third key point (point 4), again by a...
