Constructor & Destructor Documentation

MLPoissonSolver::MLPoissonSolver ( AmrBoxLib * itsAmrObject_p )

This solver only works with AmrBoxLib. In order the solver to work the cells need to be of cubic shape. Otherwise the solver stops with the error message that it did not converge (AMReX internal).

Parameters

itsAmrObject_p has information about refinemen ratios, etc.
