src.monarchs.physics.Numba.heateqn_nb.heateqn_fixedsfc(x, output, args)

Heat equation function to be passed into a solver (e.g. hybrd), but assuming a fixed surface temperature. This is split into a separate function to heateqn since the arguments are different (trying to combine them results in issues with Numba).

Parameters:

• x (float64[:]) – Starting estimate for the roots of the PDE we are trying to solve. This is by default cell.firn_temperature.

• output (float64[:]) – Output array, i.e. the values of x such that F(x) = 0. This array is handled automatically by the solver, so does not need to be initialised and explicitly entered as an argument.

• args (float64[:]) – Vector describing arguments to the system of equations being solved. This comprises many of the attributes of an IceShelf instance, and some physical variables such as specific humidity, wind etc. See extract_args_fixedsfc for more details.

Return type:

None. (the output is handled by the solver)
