Fluid Modifier
The Fluid modifier is a container for a Fluid Physics simulation. It can be useful for example, to simulate on a low-poly mesh then add a Modificador Subdivisión de Superficie after the Fluid modifier to improve the visual quality of the fluid without drastically increasing simulation times.
Opciones
As the modifier is only a container its actual options can be configured in the Physics Properties tab. See the Fluid Physics Properties for more information.
