edelta CPE streamline

Grid is 512, subgrid is 3,3,3. The vectors are projected onto the surface.

Streamline to see if it follows the twist properly. This uses a dt=0.1, with 1000 steps.

Streamline to see if it follows the twist properly. This uses a dt=1.0, with 1000 steps.

Streamline to see if it follows the twist properly. This uses a dt=1.0, with 1000 steps, no reprojection onto the surface.
