Hi all,

Do anybody know how i can monitor (in fluent) during the solving time the difference of total pressure of different interior surfaces? To monitor the pressure of a single surface is no problem. But how to calculate and monitor a combination of 2 or more mon-values?

Thank you in advance.

Cero.

cant you put in an expression? pdiff = massFlowAve(Pressure)@1-massFlowAve(Pressure)@2 like in post processor?

Unfortunately it isn't possible in Fluent. What possible is:
Quote:
> report surf-integral mass-weighted-average (40) total-pressure no
But this returns just a string without any possibility to calculate with:
Code:
 
         Mass-Weighted Average
                  Total Pressure             (pascal)
