Peng Paul Wen, Zhonghua Lu, Xiao dong Hu · Applied Mechanics and Materials · 2012
Methods for updating the computational mesh have been studied for many years and there are mainly two kinds of mesh moving algorithms known as node connectivity based and no node connectivity based respectively. As the node connectivity based mesh moving methods are universal for both structured and unstructured mesh but of high computational cost at the same time, detailed attentions are paid to in this paper to balance its advantages and disadvantages. The format and the features of the derived linear equations in node connectivity algorithms are analyzed firstly and the choice of solver for these equations are considered subsequently. Finally, parallel models for node connectivity algorithms on different parallel architectures are proposed to accelerate these algorithms. Experiments have also been accomplished to match up the analysis procedures.
