virtual Field3D solve(const Field3D &b_in, const Field3D &x0) override#
Performs the laplacian inversion y-slice by y-slice
- Parameters:
b – [in] All the y-slices of b_slice, which is the right hand side of the equation A*x_slice = b_slice
x0 – [in] All the y-slices of the variable eventually used to set BC
- Returns:
x All the y-slices of x_slice in the equation A*x_slice = b_slice

virtual int call(Solver*, BoutReal, int, int) override#
Callback function for the solver, called after timestep_ has passed
- Parameters:
solver – [in] The solver calling this monitor
time – [in] The current simulation time
iter – [in] The current simulation iteration
nout – [in] The total number of iterations for this simulation
- Returns:
non-zero if simulation should be stopped
