摘要:
我们介绍了一类基于钻石形网格的通用线性多辛积分器,用于求解哈密顿波方程。在每个钻石上,利用辛Runge-Kutta方法对PDE进行离散化。该方案通过局部填充每个钻石来推进时间,相比基于矩形网格的方法,具有更高的效率、更好的并行化能力和更易于处理边界条件。
英文摘要:
We introduce a class of general purpose linear multisymplectic integrators for Hamiltonian wave equations based on a diamond-shaped mesh. On each diamond, the PDE is discretized by a symplectic Runge--Kutta method. The scheme advances in time by filling in each diamond locally, leading to greater efficiency and parallelization and easier treatment of boundary conditions compared to methods based on rectangular meshes.
