The current sheet is where the large-scale radial magnetic field reverses sign; this template renders it directly as the Br = 0 isosurface of a MAS corona run.

To Mesh promotes the read-in grid to a mesh so the pyvista Contour filter can run on it; Contour with isosurfaces 1 and range [0, 0] draws exactly the zero-crossing surface.

Point the MAS File node at a different corona run to see how the sheet's shape changes with the underlying photospheric map; the coronal hole map is shown alongside for context on which polarity each region belongs to.

Built from: Groups ▸ Stock ▸ Surfaces ▸ Current Sheet; Groups ▸ Stock ▸ Maps ▸ Coronal Hole Map.
