nCorrectors & nNonOrthogonalCorrectors

Tushar@cfd · June 2, 2014, 08:24

Dear ALL,

By reading different threads, it can be judged that "nCorrectors & nNonOrthogonalCorrectors" are the different numbers of iteration cycles within one "timestep" and user can enter value ranging from "0" to "n".

Queries:
(1) What is the significance of the term "nCorrectors"? How the incremental value for the mentioned term improves the solution?

(2) What is "nNonOrthogonalCorrectors"? How it corrects the non-orthogonality? How the solver understands the type of Correction depending upon its value: from "0" to "n"?

I read these, still It has not clear few doubts:

(1) In case of nCorrectors: How the incremental value for the mentioned term improves the solution?

(2) In case of nNonOrthogonalCorrectors: How it corrects the non-orthogonality? depending upon its value: from "0" to "n"?

These numerals are "numbers of iteration cycles" that's fine. Where is the source code for the same?

Thanks in Advance

So far I've kept clear off the source code. But I suggest starting with the source code for pimpleFoam and going from there. Be aware that PIMPLE also includes nOuterCorrectors.
