Algebraic multigrid methods for mechanical engineering applications

Speaker: Mark Adams

Abstract

An overview of the algorithms that are deployed in the linear solver package Prometheus (available in PETSc) is presented. This includes an introduction to the primary algebraic multigrid method available in Prometheus, smoothed aggregation, as well as details of pertinent algorithmic components such as smoothers that go into a complete multigrid solver. Special attention is paid to the algorithm contributions of the author but a comprehensive overview is presented.

Application of this core linear solver engine to mechanics problems such as tires, an aircraft carrier and micro CT bone modeling problems. Efficient solves (about two minutes per linear solve) of large scale geometric nonlinear problems are presented with over on half billion degrees of freedom. Additionally, this core solution method will be extended to non positive matrices that arise from contact problems and frequency domain analysis.
