Define the Belt System

Use the Belt System tool to model a belt system.

Before creating a belt system, first create the wind tunnel and identify wheels.
  1. From the Setup ribbon, click the Belt System tool.


    Figure 1.
    By default, five patches are created on the wind tunnel ground for modeling the belt system.
    Figure 2.

  2. Define the belt system's location and sizes in the following ways:
    • Edit belts individually by selecting a belt in the Model Browser or modeling window and modifying its properties in the Property Editor.
      Figure 3.

    • Edit the belt system by clicking Belt System tool satellite icon .
      Figure 4.

If a belt system is defined and the Moving Ground checkbox is enabled in the Write to ultraFluidX dialog, the belt patches are modeled as a moving wall (moving with the inflow velocity) and the rest of the wind tunnel ground is modeled as a stationary wall. If a belt system is defined and the Moving Ground checkbox is disabled, the complete wind tunnel ground is modeled as a stationary wall. If no belt system is defined and the Moving Ground checkbox is enabled, the complete wind tunnel ground is modeled as a moving wall.
Note: The solver will always respect the settings for boundary layer suction. Any portion of the ground that is upstream of the boundary layer suction location will be treated as a slip wall.
