A Physically Motivated Solution of the Alfven Problem

Abstract

The Alfven problem has plagued explicit numerical calculations of magnetohydrodynamic fluid behavior in regions where the fluid density is relatively small but can be solved by the inclusion of terms representing the displacement current in Maxwell's Equations. This modification limits the important physical velocities to c in a realistic way and so permits much longer computational timesteps than had previously been possible. Thus the small c technique will greatly extent the usefulness of present day computers for solving these MHD problems.
