A Fully Automated Mesh Generation Tool, Phase I

Metadata Updated: May 2, 2019

This SBIR Phase I project proposes to develop a fully automated mesh generation tool which contains two parts: surface mesh generation from the imported Computer Aided Design (CAD) models and volume mesh generation from the generated surface mesh. It is well known that CAD geometry models constructed for manufacturing purposes are generally not directly useable by Computational Fluid Dynamics (CFD). Currently it usually takes several weeks to repair and defeature CAD models for surface mesh generation. The proposed effort aims to alleviate this issue by replacing the tedious CAD-fixing process with the fully automated level set approach. After obtaining high-quality surface mesh, the proposed mesh generation tool further generates high-quality volume mesh with mixed elements, taking advantages of the Cartesian cells away from the surfaces and semi-structured cells next to the surfaces. The resolution requirement is satisfied with local refinement capability.
