Hi to evrybody.
I'm planning to write a postprocessing utility in OpenFoam that read the results from a steady RANS calculation and do something on it like a random perturbation in order to produce a time history. My question is:
If i decompose my mesh, can I run in parallel my application without do anything, like in a standard solver, or have I to do something different?

Hello,

SInce you are only doing local data manipulation, you application will run in parallel with no changes.

Enjoy,

Thank you so much Hrvoje!
So, if I understood, if I work cell-by-cell without looking for other cells data, the code is allready parallelized...
Wow...

Now I have a second question:
I have to access to the single cell-elements of the vol<type>Field list in order to set in there a random perturbation.
What I want to do is:
volScalarField Up;
for (label cellID=0, cellID<nTotCells, cellID++){
Up[cellID] += randomPerturbation;
}

Where cellID is the cell-number and Up[cellID] is the value of Up in the cell cellID.
How can I do it in OpenFOAM?
Thank you!
