Preconditioned Conjugate Gradient Methods for Three Dimensional Linear Elasticity
Finite element modelling of three dimensional elasticity problems gives rise to large sparse matrices. Various preconditioning methods are developed for use in preconditioned conjugate gradient iterative solution techniques. Incomplete factorizations based on levels of fill, drop tolerance, and a two level hierarchical basis are developed. Various techniques for ensuring that the incomplete fac...

متن کاملPreconditioned Conjugate Gradient Schemes
The conjugate gradient method is a powerful algorithm to solve well-structured sparse linear systems that arise from partial diierential equations. We consider here three diierent conjugate gradient schemes for solving elliptic partial diierential equations that arise from 5-point diierence schemes: the classical CG, CG with a block diagonal-block incomplete Cholesky preconditioner and the redu...
متن کاملPreconditioned conjugate gradient method for three-dimensional non-convex enclosure geometries with diffuse and grey surfaces
Our main concern in this paper is the numerical simulation of the heat radiation exchange in a three-dimensional non-convex enclosure geometry with a diffuse and grey surface. This physical phenomena is governed by a boundary integral equation of the second kind. Due to the non-convexity of the enclosure the presence of the shadow zones must be taken into account in the heat radiation analysis....
متن کاملPreconditioned Conjugate Gradient Methods in Truncated Newton Frameworks for Large-scale Linear Classification
Truncated Newton method is one of the most effective optimization methods for large-scale linear classification. The main computational task at each Newton iteration is to approximately solve a quadratic sub-problem by an iterative procedure such as the conjugate gradient (CG) method. It is known that CG has slow convergence if the sub-problem is ill-conditioned. Preconditioned CG (PCG) methods...
