- Title
Development of a Discontinuous Galerkin Ionosphere‐Plasmasphere Model.
- Abstract
The objective of this study is to explore the application of high‐order numerical methods in ionosphere‐plasmasphere modeling. Specifically, the nodal discontinuous Galerkin method is chosen to solve the multifluid dynamical equations along the magnetic field lines. A general curvilinear magnetic field‐line‐following coordinate system is also used in the model. Numerical simulations with different combinations of number of elements (K) and polynomial orders (N) show the converging results, indicating the robustness of the algorithms and implementation. The model also captures the dawn terminator effect very well in the He+ field. Key Points: The high‐order discontinuous Galerkin method is used to solve the multifluid plasma dynamical equations along the magnetic field lineConverging results of simulations with different element size and polynomial order indicate robustness of algorithms and implementationThe model algorithms also capture the dawn terminator effect very well in the He+ density field
