To set a fluid's current dynamic grid property values as the initial state

1. Add the property values to the fluid container.

   See Add properties to fluid containers.

2. Play and stop the simulation at the frame with the fluid property values you want to set (save) as the initial state, if necessary.
3. Select the fluid container.
4. Select Fluid Effects > Set Initial State or click.
5. Maya creates a hidden initial state cache node in the Temp directory. When you save the scene, Maya creates an initial state cache node and a disk cache file and stores the file in the project’s data directory.
   • The initial state cache file is named filename_fluidShape.mcfi.
   • The node is named initialState_fluidShape.
