| Abstract | I discuss spatially and temporally adaptive implicit-explicit (IMEX) methods for parallel simulations of streamer discharges in 3D. I suggest a strategy for decreasing the time-to-solution for simulation cases by advancing the fluid equations and elliptic equations (e.g. Poisson) with different time steps, synchronizing them on a global physical time scale which is taken to be the dielectric relaxation time. A computational example of 3D branching streamers in a needle-plane geometry that uses up to 700 million grid cells is presented together with run-time diagnostics that demonstrate the unmatched efficiency of adaptive methods. ar X iv :1 80 9. 08 85 7v 1 [ ph ys ic s. pl as m -p h] 2 4 Se p 20 18 Adaptive multiscale methods for streamer discharges in 3D 2 |
