Hey Chris,
The pressure in a double-acting hydraulic cylinder in Simscape is determined by the fluid properties and the system operating conditions. The Simscape block for a double-acting hydraulic cylinder calculates the pressure based on the force balance on the piston, which is determined by the difference in pressure between the two chambers and the piston area. The pressure is assumed to be uniform within each chamber, which may not always hold true in real-world hydraulic systems.
