Difference between ptot and volPointInterpolateptot
 

Hi Foamers,

I've searched a lot in source files and I can't figure out how to know exactly what is ptot and volPointInterpolate(ptot), and especially what is the difference between theses 2 fields.

Is ptot the total pressure on the cell and volPointInterpolate(ptot) the total pressure at the Point 0 ?

Thanks for your answers.
