Results from a Long Run for the Magnetic Induction Equation



I ran my fortran program with A=(0,0,exp(-36*r*r)). Since B=del x A this would give

B=(-72(y-0.5)exp(-36*r*r),0,0).

I imposed the same uniform flow as before, i.e v=(0,-3,0) but this time I used the following parameters:

meshpoints=50,
dt=0.001,
nsteps in timeloop=1000,
coefficient of del squared=0.001

This means that I can see the results for all time up to t=1second (previously I had only ran up to 0.1seconds).

The graphs below show snap-shots of the results for time t=0.0, 0.05, 0.1, 0.15, 0.2 ......., 0.95, 1second.
