Tracer Fluid

Use the Tracer Fluid modeling object in a flow that contains miscible species where the main fluid properties are not affected by the species, such as a smoke in air.

The miscible species are modeled with a Tracer Fluid modeling object which helps you measure their diffusion and mixing in the main fluid.

The tracer fluids do not affect any of the fluid properties of the main fluid.
