This is a simulation of Pm=50, so Rm is pretty much pushed to the limit. The data files var.dat in the proc0-127 directory tree is at t=882. This is at a time where magnetic and kinetic energies are approximately in equipartition. At t=558.86 the field had been rescaled by a factor of 100, so as to reach equipartition faster.
Further details and discussions of this run can be found on pp. 57-59
of Brandenburg & Subramanian (2005).
