finding Nusselt number
Dear Sir,
i found Nusselt number code in cfd online .
what changes should be done in ControlDict file  for post processing results? I am using buoyantBoussinesqSimpleFoam

OpenFOAM Flow-over-a-flat-plate 08-09 min 10-20 sec 29-04-16, 1:37 p.m. vnarayana.wgl


I think it's easier to use ParaView to calculate Nusselt Number over a boundary. But if it does not work out you can use a utility NusseltCalc in OpenFOAM to calculate <span style="line-height: 21.4286px;">Nusselt Number for buoyancy driven flows. You may follow the pdf report given in the link below to make changes in your case file, (checkout section 4):</span>

Do let me know if you have any further problem.

I did some changes in wallHeatFlux to find Nusselt number, for that no issues .
my solver is buoyantBoussinesqSimpleFoam. to see the post processing results (Nusselt Number), i think some changes to make in ControlDict/Transport  file? if you have idea please tell me sir?
my ControlDict file

application     buoyantBoussinesqSimpleFoam;

startFrom       latestTime;

startTime       0;

stopAt          endTime;

writeFormat     ascii;

writePrecision  6;

writeCompression off;

runTimeModifiable true;
         type probes;
        name probes;
        functionObjectLibs ("");
         (0.025627 0 -0.00023237)
         (0.0518278 0 -0.000461021)
mode magnitude;
        outputControl   outputTime;
        outputInterval  1;

i don't know whether it is right or wrong ?
but i am not getting the output ? would you please help me
