Prior to setting up your flow volumes, you can specify solid bodies as cutter bodies to
automatically block the fluid flow without having to extract the overlapping bodies from
the fluid. This enables you to quickly experiment with the positions of solid objects
within the flow path.
To set a solid body as a cutter body, right-click the body in the geometry or model
tree and select Cutter Body from the context menu.
For overlapping bodies, right-click the body in the geometry or model tree and
select:
Overlapping Bodies > Set as Cutter Bodies to set the body as a cutter body
Overlapping Bodies > Exclude from Simulation to exclude the body from the simulation entirely
Overlapping Bodies > Identify to launch the Interference
tool, which detects and removes interference from clashing bodies
Click the Inlet tool then select the face that identifies where
the fluid enters the interior flow volume. Use Ctrl + click to select more faces for
additional inlets.
After the first face is selected, you will automatically be switched to Outlet.
Pressing the Ctrl key returns you to Inlet.
Click the Outlet tool then select all the faces that identify
where the fluid exits the interior flow volume.
Optionally, click the Cap tool to select a face that identifies
where the interior flow volume is capped so that the fluid does not enter or exit. Use Alt
+ click to select more faces for additional flow caps.
After the internal flow region is defined by the inlets,
outlets, and (if relevant) flow caps, the flow volume is extracted automatically. Values for
the flow inlet and outlet conditions are shown in the physics tree.
