Cube polywell, bfield magnitude in 3D

We investigate the bfield magnitude inside the cube polywell. We have already done several 2D simulations/pictures of the fields - most notably here.

We calculate a 250x250x250 grid of the cube polywell bfield magnitude and visualize the field using a 3D density map visualization tool Chimera. The data is in the Situs file format. The coils in the cube polywell are simulated by single current loops.

The generated datafile:

On the following pictures you can observe the equi-magnitudal field shape in the middle of the cube polywell. This same shape can be read off from the 2D projections but is much easier to read from these pictures. Note: bfield is a vector field, aside from magnitude the field also has a direction, these pictures only depict the magnitude in space.
