GEMPIC.jl

Geometric ElectroMagnetic Particle-In-Cell Methods

A Julia implementation of the GEMPIC

Installation

In a Julia session switch to pkg> mode to add GEMPIC:

julia>] # switch to pkg> mode
pkg> add GEMPIC

When finished, make sure that you're back to the Julian prompt (julia>) and bring GEMPIC into scope:

julia> using GEMPIC

Regression after upgrade from 0.2 to 0.3

The results for strong landau damping are not good...

Time accuracy order of Vlasov Ampere

When x and v are both 1 dimensional, and running subsystems Hp and HE (i.e., Vlasov-Ampere equations are being solved) with Strang splitting, I got imperfect second order accuracy for ex (finite element coefficients of first component of electric). When final time is chosen 1 or 0.1, these two figures shows (error of dt = 0.01)/(error of dt = 0.05) of ex, which should be about 4 (second order). We can see that accuracy order of some coefficients of ex is not second order.

Use Distributions.jl interface for particle sampling

For particle sampling, I suggest to extend this package using following instructions in the documentation.

Upgrade ParticleMeshCoupling

It works only for 1d mesh. Need to be extended until 3d.

Release the new version on the registry
