VBF-based Parallel Multigrid Algorithm with Domain Decomposition Approach for Solving Non Linear Problem on Non Uniform Mesh

摘要

This paper proposes a coordinate transformation method for non-uniform mesh size domain decomposition parallel computing with VBF (virtual boundary forecast) method-based multigrid method. The method is illustrated by solving a non-linear problem of ceramic/metal composite heat transfer. General advantages and key approach of the proposed method are in detail analysed.
