I am modifying the pimpleFoam solver to achieve a LES nesting (common operation in NWP models (numerical weather perdition)). For debug purpose, I would like to print the matrix of the linear system Ax=b.
According this page http://openfoamwiki.net/index.php/Op...es_in_OpenFOAM, those coefficients should be accessible with
scalarField *lowerPtr_; scalarField *diagPtr_; scalarField *upperPtr_;
Once those scalarField available, how to know the location of their conponant in the matrix (from scalarField(1D datas) to a matrix (2D data))?
