Prerequisites: From select Show fluid-to-fluid interfaces under
Workflow Options. You must restart Discovery for the change to take effect.
Discovery automatically detects and creates fluid-fluid
interfaces in simulations with multi-body fluid regions. Reviewing the interfaces allows you
to control the detection distance and visually diagnose the overlapping faces. Decreasing
the detection distance enforces a tighter tolerance for detecting whether faces are touching
or not. Using a smaller detection distance usually removes any spurious faces that may be
overlapping with another condition or interface. These fluid-fluid interfaces can be
reviewed by double-clicking the automatically created condition under Fluid-Fluid
Interfaces in the physics tree. Alternatively, under
Review on the Simulation tab, select
Default Fluid-Fluid Interfaces to load the Interface
Review tool. Each interface pair is shown in the model as a single dot.
-
Review the automatically generated interfaces between the fluid regions. The total
number of generated interface pairs appears on the right side of the HUD. Each interface
pair is shown in the model as a single small marker.
-
Hover over one of the spherical identifiers, Discovery highlights the surface of the interface pair. Select an identifier to show the
interface pair and total number of interfaces.
Note: Selecting an additional marker does not deselect previously
selected pairs.
-
Select the interface pair you want to review.
-
(Optional) To exclude an interface from automatic detection, select the dot
representing the interface and click Exclude from interface
detection
.
-
Optionally, specify the maximum distance of interface detection to be used in the
Max field for Detection distance.
-
By default, interface faces are grouped by body. You can choose to group them by other
topologies, like tangent faces, or to apply no grouping so that interfaces are created on
all interface faces.
