Hi all
I have simulated a flow by pimpleFoam and I need to find the min and max of pressure vs time.
I have found that during run, I can use function objects (fieldMinMax) for that
at now, how can I find min and max of pressure ?


Best Regards

Dear mechy

Max and Min of all the variables that are solved will be written on the monitor screen (for example Ux, Uy,Uz,P,....)
You can use:
Code:
| tee log -a
to write these values in a log file.
then you can use some tools like PyFoam to plot them versus time during or after the run:
Code:
pyFoamPlotRunner.py and pyFoamPlotWatcher.py
See the below link for more info:

Hi mechy,

function objects can be used even when the simulation is finished. Take a look at execFlowFunctionObjects utility.

Best,

Pablo
