Difference between p (pressure) and static pressure
 

Dear Foamers,

I am running large-eddy simulations (LES). I am confused with "pressure" and "static pressure" in OpenFOAM, see the attached screenshot below. What is the difference between them?

I read the definition of static pressure in Wikipedia, and I think when people talk about pressure, they refer it to static pressure. Then they are the same? However, I observed values of p and static(p) in OpenFOAM, they are different.

Thank you for any input.

Best,
Peter

Hello,

can this link help you?

Thank you for the thread. But still, what is the difference between "p" and "static(p)" in my screenshot? They are two different variables with different values in OpenFOAM.
