Over that pressure range I do not think you will be using the incompressible fluid assumption. So my comments from the previous post do not apply. You would have to have to explain what you are...

I am not an expert in torque converter design so do not know what charge pressure is - but if that is the base pressure of the device then yes, that would be a good reference pressure.

Replies: 30 Assigning pressure to closed fluid domains Views: 4,752 Posted By ghorrocks If the flow is incompressible in a closed domain... If the flow is incompressible in a closed domain the reference pressure is irrelevant. You can add any amount you like to it to get the reference pressure you want.

But as it now seems you have inlets and outlets then is it not a trivial matter to assign it any pressure you like? Why are you getting an unassigned pressure...

If the flow is perioidic then you should be able to use a periodic boundary, regardless of pressure level. But again, what physics is dependant on pressure? If...

So that means the absolute pressure level makes no difference, and the flow field is just offset from the reference pressure. To model the effect of pressure on the model, you need to include...
