Meshing Projects
- Real-time tessellation of Catmull-Clark subdivision surfaces:
- All-Quad Dynamic Remeshing during an unsteady laminar flow simulation over two parallel cylinders at Re = 200. The Evolution of the vorticity contours and the utilized grids is illustrated in the following figure:

All-Quad Refinement: A conforming quad-tree refinement (right) based on the gray scale function of Riemann photo (left).
- Real-time refinement of a graphical model:
Initial coarse mesh - Conforming refined mesh - Rendered image
- All-Hex Refinement: A conforming octree refinement based on the point cloud of a surface mesh representing a human face.
Unstructured All-Quad Adaptive Grid Generation with Guaranteed Quality (min angle = 45 , max angle = 135)
- Domain with multiple regions
- Lake Superior
- Multi-Element Airfoil

- Mesh insertion of a tetrahedral mesh (sphere) into a hexahedral mesh (cube): The elements of the sphere are preserved while the elements of the cube are modified to generate a connected crack-free mesh.
Input meshes - final mesh - a cross section in the final crack-free mesh
