Model Reduction for Real-time Fluids
by
Andrew Lewis
We apply a new model reduction approach to fluid simulation,
enabling the interactive manipulation of detailed 2D and 3D flows
in realtime. By decomposing the problem into subparts, our reduced
model can handle dynamic obstacles immersed in the flow: we create
parallel models for the velocity field and for each moving
boundary, and show that the coupling forces may be reduced as
well. Our results indicate that surprisingly few basis functions
are need to resolve small but visually important features such as
spinning vortices. Interestingly, our reduced model can also
control the energy dissipation throughout simulation.
