While the simulation in last post had sunspots at 22.5 degrees latitude, and their flux was not carried over 80 degrees, the time step of 100 seconds gave us quite accurate flux conservation.
But, for a sunspot placed very near the pole, we need a time step of 0.1 second for a stable numerical evolution. When run with a time step of 0.1 second, the code will approximately run for about 3 years on my laptop to complete the simulation of one solar cycle!
We seriously need to parallelise this code, if it passes all the tests we subject it to.
We also need to verify the solution it gives us, and the timespan, or the simulation time for which the results are reliable and numerically stable.
