Fluid Surface

You can use the Fluid Surface extension to simulate objects in a fluid, be it water or even wind.

To create a Fluid Surface:

  1. Select Dynamics in the Toolbox.
  2. Double-click Fluid Surface to add it to the scene or mechanism.
  3. Configure the following fields in the Properties panel.
    • Inputs
      • Fluid Density: Sets the density of the fluid (in kg/m3).
      • Fluid Velocity: Sets the velocity of the fluid along the three axes (in m/s).
      • Fluid Elevation: Sets the elevation of the fluid (in meters).
    • Parameters
      • Fluid Surface Type: There are two types of fluid surfaces you can select:
        • Planar: The planar surface is defined by a plane along the gravity axis; useful for creating an ocean or wind.
        • Mesh UV Grid: Selecting this option reveals another field, Collision Geometry, where you can select a collision geometry. Its triangle mesh defines the fluid surface; useful for creating lakes or rivers.
