本文研究了一种新的求解平稳不可压缩磁流体动力学方程的高效两步算法。该算法使用低阶有限元对(即P 1 b− P 1− P 1)来计算初始近似,即使用迷你单元(即P 1 b− P 1)来近似速度和压力,使用P 1 单元来近似磁场,然后应用高阶有限元对(即P 2− P 1− P 2)来求解同一网格上的线性系统。此外,还讨论了标准伽辽金有限元法和两步算法的收敛性分析。最后,通过数值实验验证了算法的理论和效率。
A new highly efficient two-step algorithm for the stationary incompressible magnetohydrodynamic equations is studied in this paper. The algorithm uses a lower order finite element pair (ie, P 1 b− P 1− P 1) to compute an initial approximation, that is using the Mini-element (ie, P 1 b− P 1) to approximate the velocity and pressure and P 1 element to approximate the magnetic field, then applies a higher order finite element pair (ie, P 2− P 1− P 2) to solve a linear system on the same mesh. Furthermore, the convergence analyses of standard Galerkin finite element method and the two-step algorithm are addressed. Lastly, numerical experiments are presented to verify both the theory and the efficiency of the algorithm.
