Hello, i need help in Simscape. I wanna modeling a brake the details u will find following (bremse.png). My biggest problem is the regulation with brake force and brake pressure to solver. I tried to fix the problem with a "single-Acting Hydraulic Cylinder". See Attaching(erstes.png). Ideal Force Source should be simulate my brake pedal and force. In pic "now.png" u can see what i done.
thank u in advance. I hope i can tell u what i mean. If not ask me, i try to explain in different word :).

unmark everything in local solver configuration block. You will not find any error but the issue is how to calculate the valve size from the pedal force and brake pressure relationship. The constant pressure source and cylinder arrangement is not serving the purpose for me.

Your model "now.png" is on the right track. If you connected a control signal to the S port of the valve, you would be able to see the pressure change inside the Single-Acting Hydraulic Cylinder.
For a more advanced example, see Simscape Fluids example Tandem Primary Cylinder.
