The growing release of scientific computational software does not seem to aid the implementation of complex numerical algorithms. Released libraries lack a common standard interface with regard to for instance finite element, difference or volume discretizations. And, libraries written in standard languages such as FORTRAN or c++ need not even contain the… (More)

The inverse of a boundary value problem operator can be expressed using Green’s functions. In the discrete case this is also valid. With this in mind, a preconditioner is constructed using (approximate) Green’s functions. The method is described in detail. Subsequently the method is tested for a 1-dimensional problem. For grids with local refinements the… (More)
