TPTITLE:Central Schemes for Moving Particle-based Hydrodynamics
TPABSTRACT:Central schemes are a class of Godunov-like numerical methods that replace expensive Riemann solvers with a cheaper but more diffusive flux calculations. The Kurganov-Tadmor (KT) scheme is one such central scheme that attempts to limit its diffusivity, performing admirably at the supersonic regime yet is found to cause excessive diffusion for shearing problems. Diffusion is required to maintain stability and prevent formation of spurious structures, but too much suppresses even physically relevant structures. A new method for controlling the diffusion in the KT scheme is proposed, based on determining whether the local flow is shearing or not.

LEONE:Construction has started in the lab.  There will be some money for adding sound proofing and lab renovations later in the year.  The plan to move the door on the vision lab has been put aside for now; let the directors know if the vision people coming and going is a problem.
