We are running into an issue with our model when we add in hoses. The addition of the hoses causes the model to be very slow going from a couple of seconds run time to more than 20 minutes. The system also oscillates largely in terms of the system pressures - I have attached the current model bellow and I suggest opening it and running the simulation to see the issue first hand. Not sure why this is happening but we would greatly appreciate any advice to get around this issue!
Hi Tyler,
nice model!
This is a pure numerical effect. There are two solutions (or a combination of both):
Simulation is still slow, but finishes in a reasonable time.
CPode, Cash-Karp and SDIRK deliver a similar speed.
