摘要

我们开发了弗拉索夫-安培和弗拉索夫-麦克斯韦系统的节能方案。所提出的方法将系统的总能量保持在完全离散的水平上,并且它们有一个系统的框架来结合显式和隐式时间离散化。采用具有适当数值通量的不连续伽辽金方法来保证这种性质,并且可以设计出在非结构化网格上的潜在实现。将提供基准数值测试结果。

PPPS-2013: Energy conserving numerical schemes for Vlasov-Ampere and Vlasov-Maxwell systems
We develop energy conserving schemes for Vlasov-Ampere and Vlasov-Maxwell systems. The proposed methods preserve the total energy of the system on the fully discrete level, and they have a systematic framework to incorporate explicit and implicit temporal discretizations. The discontinuous Galerkin methods with suitable numerical fluxes are used to guarantee such properties, and they could be designed with potential implementations on unstructured meshes. Benchmark numerical test results will be provided.
