In the fifth and final year of the program the research has completed defining data structures, object based programming style, and tools for a new flexible approach to scientific programming and problem solving. Problems of program complexity associated with changing models and physics as well as with joined and disjoint multiple independent patched mesh domain decompositions for treating complex geometries and resolving captured flow structures can by systematically organized within ...
A new family of computational tools is explored in the context of generic problems of interest to Army Research and Development missions. The problems are the SOCBT projectile flow and the MICOM model tactical base flow. Both problems, for which experimental data is available for comparison, have also been extensively computed by other groups with other methods, principally the central difference method of Beam and Warning. Here the techniques we ...
The research has aimed at defining data structures and completing tools for a new flexible approach to scientific programming and problem solving. Both problems of program complexity associated with changing models and physics as well as joined and disjoint multiple independent patched domain decompositions for treating complex geometries can be systematically organized within the context of the directed graph programming concept being explored. Problems and parts of problems having geometric ...
The research is aimed at providing computational tools and procedures as the building blocks to permit efficient solution and high resolution capture of flow structure in gasdynamic problems of realistically complex geometries. It has yielded a comparatively simple algebraic procedure for constructing two and three dimensional geometry fitted base level composite meshes in quadrilateral patches. The method provides complete control of coordinate distribution and gradient on all patch boundaries which ...
