********** Smoke Flow ********** .. admonition:: Reference :class: refbox :Panel: :menuselection:`Physics --> Force Fields` :Type: Smoke Flow The *Smoke Flow* force field creates a force based on a :doc:`Smoke simulation ` air flow. It applies the smoke simulation air flow velocity as a force to other simulations that use force fields. To use it you need to add a *Smoke Flow* force field and select a domain object for it. For example fire sparkles could realistically flow along the air turbulence near the simulated fire. Options ======= .. figure:: /images/physics_force-fields_types_smoke-flow_panel.png UI for a Smoke Flow force field. Domain Object An object that is used as a domain for the smoke simulation. Apply Density Adjust the force strength based on the smoke density.
