Report type to calculate pressure at sensor position

Bisht · November 9, 2015, 05:21

Hi, I am simulating multiphase flow (water and air) in a pipe. I have pressure values as experimental data to verify simulation results. The pressure values are recorded by sensors intalled at various locations in pipe (some at the position where air is a dominant fluid and some in the Water dominant region).

I am confused which report type I should use to get the pressure value at the specific location. I tried with surface average and mass flow average report over a cross sectional plane but the data is not right as the plane is also taking the cell value of the water dominant region.
Line probe is giving me only the maximum and minimum value of pressure in desired position.

Also to calculate volume fraction of water on the cross sectional plane which report is appropriate?

create a derived part > probe > point then create a report (use max or min, it doesn't matter) then assign the derived part as your input part and choose pressure (static/total/absolute/etc...) as your field function.
