ACCELERATING - Accelerating grid zones

Structured Grids

ACCELERATING zaccel [zone_selector]

Apply a constant grid acceleration of zaccel ft/sec2 in the +x direction. Only applies to structured grids, with a time step in seconds, Newton iteration, or Runge-Kutta time stepping (i.e., without local time steps). May not be used with any other moving grid option.
