Many important physical problems exhibit phenomena that require local grid resolution. Activity indicators are used by local grid refinement schemes to determine where to place or remove local grids, in order to achieve a better accuracy on the numerical procedure. We present a methodology for the s

A Cartesian grid method with solution-adaptive anisotropic refinement and coarsening is developed for simulating time-dependent incompressible flows. The Cartesian grid cells and faces are managed using an unstructured data approach, and algorithms are described for the time-accurate transient aniso
## Abstract In this study a method of equidistribution of a weight function for grid adaption is modified to produce a smoother grid which yields a more accurate solution. In the original scheme the weight function was estimated on each grid independently and a large variation in the values of the,
