X3D is the grid generation system that we use at Los Alamos and is designed for multimaterial, time-dependent, 3-D hybrid grids that are either statically adapted or evolved in time. It`s capabilities includes static and dynamic grids, hybrid grids, managing colliding surfaces, grid optimization (using reconnections, smoothing, and adaptive mesh refinement (AMR) algorithms). The X3D`s data structure can manage an arbitrary number of {open_quotes}grid objects{close_quotes} each with an arbitrary number of grid attributes. X3D uses surface geometry to build volumes by using combinations of logical and boolean operators. Point distributions can be input, generated using ray shooting techniques or defined point-by-point. Connectivity matrices are then generated automatically for all variations of hybrid grids.
