<p>Hey Damir,</p>
<p></p>
<p>in general you have to be carefull when dealing with large deflections. a linear FE-solver like karamba is made to give exact results (which of course just is an approximation of the real world by a mathematical model) for 'small' deformations, where small means something at the scale from 1/50 to 1/1000 of the length of an element.</p>
<p></p>
<p>doing form-finding with the large deformations module is better, of course, but still just a good approximation.</p>
<p>this component also sets the internal forces to zero from one step to the next, this is the reason why all the internal forces are zero in the end.</p>
<p></p>
<p>but this definition does the job with zero-length springs as joints for a scissor-system with prescribed support displacements and large deformations:</p>
