tud_lbm.operators.factory

Unified operator factory — single source of truth for operator lookup.

This module provides a generic factory function that resolves operator names to their implementations using the central registry. All operator-specific factories (in collision/, streaming/, etc) delegate to this generic factory.

Example

def build_collision_fn(scheme: str) -> CollisionOperator:

return build_operator(“collision_models”, scheme)

Functions

build_operator(→ tud_lbm.registry.OperatorTarget)

Resolve operator name to implementation.

Module Contents

tud_lbm.operators.factory.build_operator(kind: str, scheme: str) → tud_lbm.registry.OperatorTarget

Resolve operator name to implementation.

This is the single source of truth for operator factory logic. All operator-specific factories delegate to this function.

Parameters:

• kind – Operator kind (“collision_models”, “stream”, “equilibrium”, etc)

• scheme – Operator name within that kind (“bgk”, “standard”, “wb”, etc)

Returns:

The operator function/class satisfying the protocol

Return type:

OperatorTarget

Raises:

ValueError – If kind is not registered or scheme is unknown

Example

>>> op = build_operator("collision_models", "bgk")
>>> result = op(f, feq, tau)
