SmearedDeltaSource

Source: models/finite_volume/SmearedDeltaSource.py

Smeared Gaussian source for a Dirac delta distribution.

\(source[k] = mag * (1/w) / sqrt(2*pi) * exp(-0.5 * ((centers[k] - loc)/w)^2)\)

magnitude and location are global Scalars (no sub-batch); cell_centers carries the per-cell sub-batch axis (sub_batch_ndim=1); the output smeared_source inherits the cell axis. magnitude / location therefore couple densely with the per-cell output – declared in list_deriv. width and cell_centers are forward-only static parameters (the C++ side allows them to be promoted to nl inputs, but the native ModelUnitTest only checks input derivatives, so we leave that plumbing for a follow-on).
