FROSch (Fast and Robust Overlapping Schwarz)
FROSch (Fast and Robust Overlapping Schwarz) is a framework for parallel overlapping Schwarz preconditioners in Trilinos. It is designed to be used as an algebraic solver for discrete problems arising from continuum mechanical problems. The framework is part of the Trilinos package ShyLU and it offers a range of functions for the construction and combination of various Schwarz preconditioners.
The FROSch code is availble on GitHub as part of Trilinos. For more information, see About and the ShyLU user guide.
