论文摘要
在本文中，我们提出了一种用于vlasov- poisson方程的新型粒子方法。与常规粒子方法不同，粒子不是解释为点电荷，而是分布函数的点值。在粒子之间，使用无网插插一起重建分布函数。我们的数值实验证实，这种方法可显着提高准确性和降噪。同时，保留了传统方案的许多好处。
In this paper we present a novel particle method for the Vlasov--Poisson equation. Unlike in conventional particle methods, the particles are not interpreted as point charges, but as point values of the distribution function. In between the particles, the distribution function is reconstructed using mesh-free interpolation. Our numerical experiments confirm that this approach results in significantly increased accuracy and noise reduction. At the same time, many benefits of the conventional schemes are preserved.
