It is possible to shift the starting point of the cached fluid simulation.

Offset

This parameter is only relevant if your simulation is in → "Cache" mode. With "Offset" you are able to specify an individual frame offset for every fluid, rigid, elastic, or mesh node. This way it is possible to synchronize simulations with other animated Maya scene elements. Alternatively you can also define a global → "Frame Offset", valid for all simulation nodes. The global "Frame Offset" also affects the individual node offsets:

Total offset = frame offset + node-specific offset
