In am using a fixed Displacement motor in a simulation where in some conditions may act as a pump.
I noticed a non-physical behavior in case the motor inlet is closed while still turning (shaft is turned by an external torque), The torque load rise unlimited.
After analyzing and checking the motor in the attached simple simulation, I notice that the motor creates a non-physical *UNLIMITED* negative pressure in the inlet.
This is non-physical because in an ideal vacuum there shall be a zero pressure in the inlet and thus the pressure difference cannot exceed 1-bar.
This behavior is obviously misleading and may lead to mistakes in simulation results.
I also checked it with a pump and got same results.
I attached the simple sim file and results.
Did anyone notice that? Am I missing something or this is a bug that needs a fix?
