Improved Jacobi iterative method for hybrid grid and its application

  • 摘要: LU-SGS因有较高的鲁棒性和小的内存需求而得到广泛应用,然而用于混合网格计算前需要进行网格排序和分组来实现算法并行;此外,LU-SGS格式收敛效率不高。针对这些缺点,本文提出了一种改进的适用于复杂混合网格的雅可比迭代方法,无需网格排序和分组就可实现算法的并行化,且有较快的收敛速度。该方法编程实现简单,易于采用OpenMP实现并行。算例研究表明,相比于LU-SGS格式,在各来流条件下,本文提出的方法收敛速度更快,鲁棒性好,并行和串行结果一致,且内存需求增加很少。
