• Fast transition from large blue-light scan data to surface/volume meshes for high end multiphysical solvers. Reduction in process time from 3 months to 2 weeks. Goal: 1 day turnaround time.

• Automatic CAD repair tools to minimize processing time/labor for creating water-tight models.

• Generation of high-order curvilinear surface and volume meshes consistent with high-order solvers in creating large cell sizes with geometric fidelity to minimize computing resources for large-scale problems.

• Template approach for quick turnaround gridding with automated parametric geometry creation for design and optimization of complex problems.

• Customized and timely user support.

Multi-Order Meshing

Adaptive Meshing

CAD2Mesh creates all higher order vertices up to a specified order • Uses geometry information to capture

curvature • Local to global parametric method derived

from adaptive techniques • Faster than an initial mapping technique,

unlimited order For triangle element, # of control points (n+1)(n+2)/2: 3rd-order:10 points; 7th-order:36pts

Viscous Unstructured Meshing

CAD2Mesh automatically creates the extrusion layer from the fully connected geometry surface mesh, including triangles and quads. Advancing front volume mesh then generated using tet/pyramid combination.

Template-Based Meshing

Automated parametric geometry creation and meshing for classes of geometries • Variables parameterized to create different

geometries and meshes within a class • May be used for optimization studies • requires custom dialogs
