How does Fluent calculate surface integral area weighted average in transient models?

hnorth · June 10, 2020, 15:03

I am trying to calculate pressure drop and found the following solution. "Report--> Surface integrals--> Report type (Area weighted Average)--> Field variable (Pressure, either static, dynamic or total). Choose the inlet and outlet from the list and find the difference to get the pressure drop." My questions, is the result averaged over all my time steps?
Thanks!

It will calculate every time step.
