i'am a beginner with matlab and simulink, and for a thesis project i'am trying to set some simulations to have base results for the successive experimental tests.
In this specific case, i'am trying to simulate a very simple system, the will become more complex in the successive steps: a force source that is emulating a force given by a compression spring, and i have to verify if the spring force is enough to overcome a load, that is given by the other force source. In the middle i have a Loaded-Contact Translational Friction to simulate the load that i given by a torsional spring on my physical system.
When i try to simulate, i have the errors that are showed in the image, and i don't what is the problem. Could be related to a missing degree of freedom between the 2 sources?
