I'm using OpenFOAM-1.5-dev,and confusing with the parameters in fvSolution.
firstly, what are the meaning of "relTol" and "tolerance"? and are they differences? how to set by commonly?
secondly, what is the meaning of "nCellsInCoarsestLevel"? the mesh is better, and the value of "nCellsInCoarsestLevel" is less ?

This is briefly covered in the User Guide, but
When value of the residual in the linear system solver that is scaled using the definition here falls below tolerance, it will stop the linear system solver.
When the value of the ratio of the current residual over the initial residual (where the initial residual has been scaled using the above procedure) falls below relTol, the linear system solver will stop.
start with ncellsincoarsestlevel
Hope this helps.
