Updates on Regrid and Using Cartesian Grid for a Spherical Problem

Desity and Field Plot of Final Frame

Tried to reproduce this figure from the 2018 paper:

Now, however, the Cartesian grid is too grainy and leads to ring like structures (Nodal plot is slightly better).

Trimmed down the boundary and increased resolution (2x) to get this:

But max field has reduced by ~22%, possibly due to new boudary conditions.

Regrid

Regrid was successful to Lv. 4 for the simulation we were using.

The int data type was going into overflow by a bit.

Here are the resulting field lines:

However, when I try to do the same with the higher resolution simulation, it runs out of time. So it probably needs >5x the time from the lower resolution case or there could be another bug.
