An asynchronous interface relaxation method for multi-domain/multi-physics problems

Abstract

An approach for the solution of multi-domain and multi-physics problems is the application of an interface relaxation (IR) method to treat the solution on the common boundaries between domains of the original problem. This solution process is more efficient than other techniques, but still remains quite computationally intensive and the inherently parallel solution of the underlying problems does not scale to the overall method. This paper presents an asynchronous parallel algorithm of a specific IR method, named GEO. The performance results in terms of convergence speed and execution time demonstrate the efficiency of the proposed algorithm towards the solution of large-scale multi-domain and multi-physics problems. © 2016 Author(s).
