Following is a simple snippet that creates a new current sheet and runs the calculations:
import reconnection as r
psi_0, j_0, eta, nu = r.Reconnection.std_input(50, 50)
test = r.Reconnection(psi_0, j_0, eta, nu)
test.run(500, 1e-1)
r.Reconnection.std_input returns a standard initial condition and certain values for
eta and nu, which represent the resistivity and viscosity of the plasma, taken as
constant throughout the sheet. It takes as parameters the spatial resolution of the
sheet, and as optional arguments different values for eta and nu.
r.Reconnection(psi_0, j_0, eta, nu) returns the reconnection model with given
initial conditions.
obj.run(Niter, dt) runs the simulation with Niter iterations of dt time-step.
A variety of post-treatment and plotting methods are available.
