View source for Snip calculate field value at point

The original question (as posten on [http://openfoam.cfd-online.com/forum/messages/1/438.html the Message board]) was: ''Given a position as (x,y,z), I want the u or p value in this point by using interpolation.''

== Doing the interpolation by yourself ==

<cpp>
vector probePoint(x,y,z);
label probeCell = mesh.findCell(probePoint);

const labelList& probeCellNeighbours = mesh.cellCells()[probeCell];

forAll(probeCellNeighbours, cellI)
{
  // Do your stuff
}
</cpp>

== Using OpenFOAM's interpolation classes ==
