I do not understand this statement.

 

Then test by forcing a partition that cuts the surface(s) of interest: don't rely on Fluent's automatic method as it's intended to maximise efficiency gains. 

 

what do you mean by intended to maximize efficiency gains?

 

my question is, i will use the UDF in Section 7.8 on a simple fully developed laminar flow in a pipe problem as described above.

I will set int surface_thread_id=3; (in the second line of the udf printed, this is the thread ID of the inlet) 

and when the second to last line is executed,

 

This one:

Message("Average pressure on Surface %d is %f (Pa)\n",surface_thread_id,(total_force/total_area));

 

will this print/display on the console the average pressure value which is equal to the area-weighted average of pressure (calculated from surface integrals)?

 

please let me know.
