Nika Ragua demonstrates how to create a volcanic eruption effect as an example of getting Softimage ICE particles driving a simulation with Autodesk Maya Fluids.
Tutorial how to drive Maya Fluids with Softimage ICE particles
If you have both Softimage and Maya, you can create a simulation in Softimage using ICE and then export that cached simulation to Maya. Nika mentions that a simulation workflow like this would be better for an artist using ICE, creating the particle effects with a bit of control, focusing more on the visual aspects rather than the technical, and then use Maya for rendering the simulation using Maya Fluids.
