A recent paper by Huang et al. [Computer Physics Communications 207, 123 (2016)] thoroughly analyzed the Finite Grid Instability(FGI) and spectral fidelity of standard Particle-In-Cell (PIC) methods. Numerical experiments were carried out to demonstrate the FGIs for two PIC methods, the energy-conserving algorithm and the momentum-conserving algorithm. The paper also suggested that similar numerical experiments should be performed to test the newly developed Structure-Preserving Geometric (SPG… Expand

A big-isotropic structure E is an isotropic subbundle of TM⊕T*M, endowed with the metric defined by pairing. The structure E is said to be integrable if the Courant bracket [X,Y]∊ΓE, ∀X,Y∊ΓE. Then,… Expand
