• 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
