Abstract

This paper proposes a virtual boundary condition forecast method in parallel multi-grid algorithm design with domain decomposition for solving non-linear transient problem. Numerical results of non-linear transient heat transfer problem by the algorithm in a PVM network computing environment show that the algorithm has high parallel efficiency.

Key words: Multi-Grid, Domain Decomposition, Virtual Boundary, Boundary Condition Forecast
