Selectively reduced bi-cubic interpolation for ink-jet simulations on quadrilateral grids

摘要

A selectively reduced bi-cubic interpolation on quadrilateral grids for level set re-distancing improves finite-difference-based ink-jet simulation. The "bi-cubic" nature of the interpolation helps the scheme conserve droplet mass. The "selectively reduced" logic prevents the higher-order simulation algorithm from introducing new instability factors.
