Pipe (TL) fluid compressibility problem

Hello whenever I uncheck the compressibility box my model can't run anymore can anyone help please.

Any reason why you'd like to turn it off?

Is the closed loop system the same one you mentioned in another question (https://www.mathworks.com/matlabcentral/answers/2111661-rservoir-tl)? I feel like this model may suffer from pressure/temperature build-up, too, in its current form.

I rarely see turning of compressibility is the solution to any issue or has any advantage.

@Yifeng Tang Thank you again for your answer! I actually didn't want to turn it off but my lab partner advised me to do so, even thought I think it is necessary to keep it on. Regarding my other question it is not entirely the same model. This one is a more simplified model.

I see. I think the nature of the issues is the same. I'll put a note in the Answers to redirect to the other thread then.
