Dominio

Fluid guides are used to apply forces onto the simulation. They are like simple external forces but also seek to preserve the physically accurate flow of the fluid. The Guides panel allows you to adjust guiding forces globally, i.e. for the entire domain. Enabling the guides hints the fluid solver to use the more accurate, but also computationally more expensive pressure solving step.

Even when there are no guiding objects baked or there is no guiding domain attached, the fluid solver will still perform the more expensive pressure guiding algorithm if guiding is enabled. It is therefore recommended to only enable Guides when there is a clear intention to use guiding in the simulation.

Fluid guiding is an implementation of Primal-Dual Optimization for Fluids.

Influencia

Controls the lag of the guiding. A larger value (also known as the “alpha” guiding value) results in a greater lag.

Tamaño

This setting determines the size of the vortices that the guiding produces. A greater guiding size (also known as the blur radius or “beta” guiding value) results in larger vortices.

Factor de velocidad

All guiding velocities are multiplied by this factor. That is, every cell of the guiding grid, which has the same size as the domain object, is multiplied by this factor.

Origen de velocidad

Guiding velocities can either come from objects that move inside the domain or from other fluid domains.

Efector

All effector objects inside the domain will be considered for the global guiding velocity grid. Once effector objects have been baked it is not possible to change the fluid domain resolution anymore.

Dominio

When using another fluid domain as the guiding velocity source this domain may have a different resolution and may also be of a different type (e.g. the guiding domain is of type Gas while the actual domain with the guiding effect in it is of type Liquid).

In order to use a domain as the velocity source, this domain needs to be baked already.

Dominio guía

Al usar Dominio como origen de la velocidad, este campo servirá para seleccionar el objeto de dominio que actuará como guía.

Capturar guías, Liberar guías

Esta opción sólo se encontrará disponible al usar el tipo de caché Modular y Efector como Origen de velocidad. Capturar guías grabará las velocidades de los vértices de los objetos efectores al disco. Deberá ser usado antes de capturar la simulación de fluidos.

The progress will be displayed in the status bar. Pressing Esc will pause the simulation.

Una vez que la simulación haya sido capturada, el caché podrá ser eliminado, presionando Liberar guías. Será posible pausar o reanudar un proceso de captura de guías.
