Explanation of "solve"-function
Join Date: May 2010

Hello out there in the big OpenFOAM-world.
Is there anybody who can really explain to me the solve-function?
If I look at
->solve(psiCmpt, sourceCmpt, cmpt);
- But where is that solver really defined?
- Where can i find the actual definition of the function "solve()"?
And if there is somebody really knowing about that solve-function:
- Is there a way to call that solve() for a specific cell only?
I am kind of lost with the C++ stuff or at least inside the structure of OpenFOAM, so any help is welcome!

Hi Bernhard, did you find any information regarding the functionality of the solve() function? Thanks.

The solve function you are looking at is a virtual function ( http://foam.sourceforge.net/docs/cpp/a02380.html ) which is redefined for each solver (diagonalSolver, GAMGSolver, ...).
If you want to solve a linear system directly in a cell or a limited number of cells, you probably want to follow a simpler way. You can, for example, use a scalarSquareMatrix and use LU decomposition on it (OF can do it).
GeekoCFD - A free distribution based on openSUSE 64 bit with CFD tools, including OpenFOAM. Available as in both physical and virtual formats.
OpenQBMM - An open-source implementation of quadrature-based moment methods.
To obtain more accurate answers, please specify the version of OpenFOAM you are using.
