In a recent attempt to run a fluid flow model to determine delta pressure, the solver did not appear to produce any pressure difference data. The results were all very close to 14.7 psi, where I was able to get 100+ psi results with the same model before. Its seeming like there's some accumulation in the program limiting the resources, since I have dome many runs on this same model. Has anyone run into this problem by chance, and if so, do you know what can be done to resolve it? Thank you.
