Locally Adaptive Remeshing Scheme for Calculating Fluid Instabilities

LAM is a two dimensional Eulerian hydro code with local adaption that uses a Van Leer limiter, artificial viscosity, and a staggered mesh (Crowley 1992). It differs from the Goduonov schemes used elsewhere (Colella and Graz 1985), but this formulation makes it easier to introduce additional physics to the code. Two distinct advantages of the present code are a conformal quadrilateral mesh option and a grow capability. The code is presently being extended to three dimensions.
