有界区域上的粒子与样条

On Particles and Splines in Bounded Domains

Matthias Kirchhart

AI总结:

本文提出一种结合粒子场、笛卡尔张量积样条与虚拟区域法的数值方案,仅需边界拟合网格即可在有界区域求解对流问题,并证明了其在 $W^{s,p}$-范数下的稳定性与一致性。

摘要:

我们提出数值方案,使其能在一般有界区域中应用粒子方法求解对流问题。这些方案将粒子场与笛卡尔张量积样条及虚拟区域法相结合。其实现仅需区域边界的拟合网格,而非区域本身,其中使用了非拟合笛卡尔网格。我们在 $W^{s,p}$-范数($s\in\mathbb{R}$,$1<p\leq\infty$)下建立了这些方案的稳定性和一致性。

英文摘要:

We propose numerical schemes that enable the application of particle methods for advection problems in general bounded domains. These schemes combine particle fields with Cartesian tensor product splines and a fictitious domain approach. Their implementation only requires a fitted mesh of the domain's boundary, and not the domain itself, where an unfitted Cartesian grid is used. We establish the stability and consistency of these schemes in $W^{s,p}$-norms, $s\in\mathbb{R}$, $1<p\leq\infty$.
