Cannot simulate flow rate changes in response to pressure differences in the air chamber
Two chambers with different initial pressures are connected by a Local Restriction (MA), which is commanded to close until a certain point in time and open after that time.
In this case, we expected that the chambers with different pressures would be connected at the timing when Local Restriction was opened, and air would move from the chamber with the higher pressure to the chamber with the lower pressure.
However, the result was that terminal A of Local Restriction was below the minimum effective pressure and an error occurred.
The settings are: chamber 1 initial pressure is 10.13 kPa; chamber 2 initial pressure is 101.3 kPa; Local Restriction is fully opened after 360 second.

Please tell me how to create a model in which air moves according to the pressure difference between chambers.
The attached image shows the model and output.Cannot simulate flow rate changes in response to pressure differences in the air chamber
