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
