摘      要：We considerwhether implicit simulation techniques can be extended in time and space scales to magnetohydrodynamics without any change but the addition of *** goal is to couple fluid and kinetic models together for application to multi-scale *** a simulation framework,transition from one model to the other would occur not by a change of algorithm,but by a change of *** would greatly simplify the *** the way,we have found new ways to impose consistent boundary conditions for the field solver that result in charge and energy conservation,and establish that numerically-generated stochastic heating is the problem to *** an MHD-like problem,collisions are clearly necessary to reduce the stochastic *** collisions,the heating rate is *** collisions,the heating rate is significantly reduced.
