how to calculate average pressure
Dear friends
I did transient analysis. inlet is velocity(t) and outlet is 0 Pa. I would like to calculate the average pressure inside the domain or at a point inside the domain. for this I have created a plane and I use a function calculator and I set the following parameters function > area average ; Location > plane 1: Variable > Total pressure. Please confirm is the procedure is correct? Thank you Regards Govind 
Dear friends
I have created a xy plane. ( flow is in the z direction) when I measure the average pressure I got negative value . How this is possible. I set pressure at the outlet zero. Please help me Regards Govind
