Multigrid contact detection method

Physical Review E, 2007
Contact detection is a general problem of many physical simulations. This work presents a O(N) multigrid method for general contact detection problems (MGCD). The multigrid idea is integrated with contact detection problems. Both the time complexity and memory consumption of the MGCD are O(N).

Fully Adaptive Multigrid Methods

SIAM Journal on Numerical Analysis, 1993
Summary: Adaptivity is a key concept for the effective numerical solution of differential equations. The multilevel solution of elliptic partial differential equations can be combined with adaptive mesh refinement and an adaptive choice of the discretization order.

SCHWARZ ALTERNATING METHOD AND MULTIGRID METHOD

Acta Mathematica Scientia, 1987
The author considers asynchronous parallel algorithms which arise from two different combinations of the Schwarz alternating method with the multigrid method: In the first approach the original problem, the variational problem find \(u\in H\) \(1_ 0(\Omega)\) such that \(a(u,v)=(f,v)\) for all \(v\in H\) \(1_ 0(\Omega)\) is divided into p related ...

Asynchronous Multigrid Methods

2019 IEEE International Parallel and Distributed Processing Symposium (IPDPS), 2019
Reducing synchronization in iterative methods for solving large sparse linear systems may become one of the most important goals for such solvers on exascale computers. Research in asynchronous iterative methods has primarily considered basic iterative methods. In this paper, we examine how multigrid methods can be executed asynchronously.
