Hello,

I'm trying to substract via Paraview two plane of my OpenFoam simulation in order to have a Pressure coefficient ((Pext-Pint)/Pref).

For that, I generated a plan which represent the external pressure of my façade, and a plan which represent the internal pressure of my façade.

I use after that the PythonCalculator but as i do not have the exact same amount of cells in each plans, i have en error message.

Does someone have an idea about how can i do some operations between these two plans even if they don't have the same amount of cells ?

Would be very grateful,

Thanks,

Adak
