Title:

    Implicit FEM and fluid coupling on GPU for interactive multiphysics simulation

Presenter(s)/Author(s):



Abstract:


    We present a method to implement on the GPU an implicit FEM solver which is fast and stable enough to handle interactions and collisions. We combine this method with GPU-based fluids [Zhang et al. 2008] and collision detection [Allard et al. 2010] to achieve interactive multiphysics simulations entirely running on the GPU.
