Parallel functions

chris1980 · July 27, 2006, 02:51

Hi I want to write a solver which is able to run in parallel.

I was wondering if weightedAverage() calculates the average of the hole domain?

I know there are some special function like gSum, gAverage. Is there a doc about the existing parallel functions?

All the functions working on GeometricFields (volScalarField, surfaceVectorField etc.) tend to be parallel aware. See the (out of date) programmers guide chap. 1.

Mattijs,

what do you mean "tend to be parallel aware".

What does the function weightedAverage do a global domain average or a local domain average?

global.

Mattijs,

you said all functions working on GeometricFields are global.
I was wondering if there is an internalField() function which returns field defined on the local cells ? Or is there a workaround to do this ?
