Examples of org.openpixi.pixi.physics.grid.ChargeConservingCIC

org.openpixi.pixi.physics.grid.ChargeConservingCIC
Interpolates current from the particles to the grid in a way s.t. the continuity equation divJ = - drho/dt is fulfilled. This condition depends also on the way how the charge density is calculated. This algorithm assumes area weighting used in the CloudInCell algorithm. NOTE: On a coarser grid this algorithm will give a lower current compared to a finer grid when the particle travels the same absolute distance in both cases.
