writing phi as postProcessing

Hi
how can write phi after the run in folders.
I use rhoCentralFoam that has phi in itself.
@ Bruno: dear Bruno is it applicable by the same function as "rho" field in prism case?

Hi Ehsan,

This is a bit more complicated than using a function object.

The problem is that you no longer want to run a solver, which leads to the need to use another application for re-calculating "phi". Worst is that calculating "phi" depends on whether it's done in compressible or incompressible form...

In theory, the idea would be to base ourselves on the specificHeat application that was done some time ago: http://www.cfd-online.com/Forums/ope...tml#post418191 - post #17

Then use the code from the solver that you used... was it rhoCentralFoam?

Anyway, I don't know exactly what you need here and if you still need it.

Best regards,
Bruno
