Benchmark modeling and 3D applications of solidification and macro-segregation based on an operator-splitting and fully decoupled scheme with term-wise matrix assembly

Abstract

Highlights• An operator-splitting and matrix-based scheme is proposed.• This fully decoupled scheme enhances implementability.• The mix of vectorization and forward matrix assembly benefits 3D applications.• A term-wise strategy is suggested to balance the computational costs and the complexity of implementation.• Plenty of benchmark cases validate the accuracy and efficiency of this method.
