Christopher Batty	Title : Towards divergence-free interpolation Abstract: The animation of (effectively) incompressible liquids assumes that the flow is divergence-free. However, in typical numerical methods, this incompressibility constraint is only enforced at the discrete level, i.e., the finite difference approximation of the divergence operator is zero, but the interpolated smooth velocity field is usually not analytically divergence-free, which leads to errors in the flow. I'll discuss some preliminary work that aims to address this issue.

Title : Towards divergence-free interpolation
Abstract:
The animation of (effectively) incompressible liquids assumes that the flow is divergence-free. However, in typical numerical methods, this incompressibility constraint is only enforced at the discrete level, i.e., the finite difference approximation of the divergence operator is zero, but the interpolated smooth velocity field is usually not *analytically* divergence-free, which leads to errors in the flow. I'll discuss some preliminary work that aims to address this issue.
