fdtdx.apply_params

fdtdx.apply_params(arrays, objects, params, key=None, **transform_kwargs)

Applies parameters to devices and updates source states.

Parameters:

• arrays (ArrayContainer) – Container with field arrays

• objects (ObjectContainer) – Container with simulation objects

• params (ParameterContainer) – Container with device parameters

• key (jax.Array | None) – JAX random key for source updates. When None (the default) a deterministic key is derived from _DEFAULT_KEY_SEED.

• **transform_kwargs – Keyword arguments passed to the parameter transformation.

Returns:

A tuple containing:

• Updated ArrayContainer with applied device parameters

• Updated ObjectContainer with new source states

• Dictionary with parameter application info

Return type:

tuple[ArrayContainer, ObjectContainer, dict[str, Any]]
