PEBBLES is an Algebraic Multigrid package for solving large, (sparse, symmetric) positive definite linear equations which arise in a Finite Element (Finite Difference, Finite Integration Technique) discretization of elliptic partial differential equations of second order. The interface to a Finite Element program is based on the element stiffness matrices or the matrix itself. PEBBLES is written in C++ and is supplied with an C++, C and an F77 interface (an F90 interface is also possible).
PEBBLES is a research code where especially the following items are realized:
