報(bào)告人簡(jiǎn)介：杜彬彬：理學(xué)博士，西南財(cái)經(jīng)大學(xué)講師，碩士生導(dǎo)師。主要研究不可壓縮流問(wèn)題的高效算法和理論分析。主要涉及迭代，多水平，并行算法等。在JSC，NMPDE，CICP等國(guó)際期刊上發(fā)表數(shù)篇SCI論文。

報(bào)告內(nèi)容簡(jiǎn)介：We consider the two-level methods based on Arrow–Hurwicz (A-H) iteration for solving the stationary incompressible magnetohydrodynamics problem. The methods carry out some A-H iterations on the coarse mesh, improve the obtained solutions by using one-step scheme on the fine mesh. Such methods enjoy some advantages including that the number of A-H iterations can be flexibly and controllably selected, and they are valid for high hydrodynamic Reynolds number. The convergence analyses are established and various numerical experiments are performed to validate and illustrate the stability, accuracy, and efficiency of the new methods.

歡迎廣大師生參加！
