spectral_galerkin_heat.physics
==============================

.. py:module:: spectral_galerkin_heat.physics

.. autoapi-nested-parse::

   Physics kernels: CPU and GPU spectral method implementations.

   **Public API:**
   - ``spectral_cpu_kernels``: High-level solver functions for CPU backend
   - ``spectral_gpu_kernels``: GPU-backend solver functions (requires CuPy; import the submodule directly)
   - ``spectral_helpers``: Utility functions for spectral computations

   Public symbols from each kernel module are the high-level functions
   called by the solver (e.g. update_modes_etd1, compute_latent_heat_source).
   Internal helpers (prefixed with ``_``) are not part of the public API.

   **Internal helpers in spectral_helpers:**
   - ``_C_coef``: Normalization coefficients (private)
   - ``_calculate_subgrid_indices``: Fine-mesh box centering (private)
