Creating a Liquid Simulation

Procedure

To create a fluid simulation:

  1. From the Create panel, choose Geometry > Fluids, then click the Liquid button.
    Alternatively, you can also create a Liquid object using the menu:
    • Default menu: Animation menu > Fluids > Liquid
    • Alt menu: Animation menu > Fluids > Liquid
  2. From the Modify panel, in the Emitters rollout under Icon Type, choose the type of emitter to use: either Sphere, Box, Plane, or a custom shape.
  3. Adjust the parameters as required.
  4. Drag in the viewport to place and size the Liquids logo that shows the liquid object. The object is added to the scene, with an emitter and voxel grid (if enabled) also shown.
  5. In the Setup rollout, click Simulation View to open the Simulation View window.
  6. In the Simulation View window:
    • Use the Display Settings panel to specify how to display liquids and foam in the viewport.
    • Use the Liquid Attributes panel to adjust the emitter and add colliders, kill planes, foam masks, and motion fields. Use this panel to also create a guide system if suitable.
    • Use the Solver Parameters panel to adjust the properties for the solver created for the liquid. Adjust simulation parameters such as scale and voxel size, and liquid parameters such as surface tension and viscosity. You can also configure additional options for objects and helpers involved in the simulation.
    • In the Management System area, run the solver so you can view the simulation and make further adjustments. You can solve the liquid component , the foam component , the mesh , or any combination of the three. Typically you would solve the liquid first, the foam, and then finally the mesh once you are ready to render.
    • Add and clone solvers to experiment with the simulation, and to troubleshoot problems like particle leakage. As the simulation improves, you can decrease the voxel size to see higher resolution previews and make your final tweaks.
    • When you are satisfied with the result, use the Render Settings panel to set options before rendering the simulation.
You can stop a solve at any time, or pause a simulation and then resume when ready.
Warning: Changing conversion parameters such as voxel scaling during a paused solve is not recommended. In addition, starting a simulation while another is already running may cause your computer to become slow or unresponsive.
