ode_heatloop(
    time: ndarray,
    dt: float,
    qscale: ndarray,
    T_f_in_derivs: ndarray,
    b2g: B2G,
) -> np.ndarray

Integrates the borehole heat transfer equations over time using an ODE solver.

Solves the transient 2D axisymmetric heat transfer between fluid, pipes, borehole, and ground. Uses a simple explicit upwind scheme and Dirichlet boundary conditions for the inlet temperatures.

Parameters:

Name	Type	Description	Default
time	ndarray	Array of time points [h] for integration.	required
dt	float	Timestep scaling in seconds.	required
qscale	ndarray	Time array of scaling factors of the reference flow (time dimension)	required
T_f_in_derivs	ndarray	Time derivative of inlet fluid temperature [°C/h].	required
b2g	B2G	Borehole-to-ground model containing pipe and axisymmetric grid information.	required

Returns:

Type	Description
ndarray	Temperature array of shape (len(time), nx, ny, nz), where nx, ny, nz are the dimensions of b2g.ag (grid).
