freegs.fieldtracer.traceFieldLines#
- freegs.fieldtracer.traceFieldLines(eq, solwidth=0.03, nlines=10, nturns=50, npoints=200, axis=None)[source]#
Trace field lines from the outboard midplane
Inputs#
- eq:
Equilibrium object
- solwidth:
The width of the SOL in meters
- nlines:
Number of field lines to follow
- nturns:
Number of times around the tokamak to follow
- npoints:
Maximum number of points per line. May hit a wall
- axis:
Matplotlib figure Axis. If given, field lines are plotted on the axis
- returns:
forward (
LineCoordinates) – The forward field line coordinatesbackward (
LineCoordinates) – The backward field line coordinates
Example
>>> forward, backward = traceFieldLines(eq)
