Toolkit for Automatic Mesh Generation and Adaptation to Control Discretization Errors and Geometry Changes

This project will develop a general purpose automatic meshing toolkit appropriate for implementing automated, adaptive analysis systems. The new toolkit will build off of existing capabilities that include isotropic surface and volume meshing direct fromCAD data, boundary layer meshing for CFD applications, and adaptive mesh procedures. New capabilities to be added include anisotropic surface and volume meshing and remeshing, mesh modification techniques to introduce anisotropy, a generalized errorindication framework with specific techniques for compressible flow problems and solution transfer techniques. The combination of the existing and new capabilities will result in a comprehensive toolkit that will be applicable to many different problemdomains.The software to be developed will be used by companies that develop Computer Aided Engineering (CAE) software for a number of different domains. Having these techniques available as an easy to use toolkit will enable these companies to more quicklyand cheaply develop advanced software for physics-based modeling and simulation. The techniques to be developed have obvious applications in the Computational Fluid Dynamics area, however they will also be useful in virtually any type of simulation.Simmetrix will market and license this software to companies developing CAE software.
