| - Meshing Algorithm Development: Had developed three algorithms for all-quadrilateral mesh generation with guaranteed angle bounds: 1. Quadtree-based all-quadrilateral mesh generation with feature preservation; 2. Hexagon-based all-quadrilateral mesh generation; 3. Matching interior and exterior meshes and sharp feature preservation. Now working on all-hexahedral meshing algorithm based on the adaptive octree using 2-refinement templates. | |
| - Mesh Generation: Used sweeping method to generate a structural hexahedral control mesh for a heart model from CT data; Used octree-based isocontouring method and deformation registration to dynamically generate hexahedral meshes for a lung model in different phases from MRI data. | |
| - Mesh Quality Improvement: Improved the overall quality of the high-fidelity tetrahedral mesh for fluid-structure interaction analysis of aneurysms. Maximized the minimum volume and scaled Jacobian of the tetrahedral elements by pillowing, smoothing, and local optimization. Eliminated non-manifold elements by edge contraction. | |
| - Simulation: For lung cancer treatment planning, simulated bioheat transfer of laser therapy in ANSYS. Improved the bioheat transfer equation by considering the air effect. Optimized the number, power and location of laser probes used in the therapy via bubble packing algorithm. | |
| - Software Development: Developing "Mesh Viewer" for mesh visualization and modification, which can visualize common meshes, NURBS and solid NURBS models with colors. Visual C++, OpenGL and GLUT are used in the development, and QT will be used to improve the User Interface in future. |

| - Force Distribution of a Piezoelectric Thin File with Defects and Inclusions: Obtained the solution of the stress field induced by the eigenstrain of an ellipsoidal inclusion in the film/substrate half-space via Fourier transforms and Stroh's eigenrelation equations. Investigated the effect of thin film's thickness on the stress field. Introduced a rule to simplify the calculation of similar problem. |

| - Dynamic Responds of the Foundation of a Large-Sized Industrial Printer: Simplified the 3-D foundation into a 2-D mesh using beam elements and plane elements. Constructed the mesh and finished the simulation in ANSYS using APDL. Determined the natural frequencies of the foundation. Reduced the amplitude of the dynamic responds of the printer foundation under loads. | |
| - Feature Study of Carbon Nanotube: Investigated the initial geometrical features of single-walled carbon nanotube via atomistic-based continuum theory. Determined the relationship between carbon covalent bond and bond angle. Compared the difference between armchair and zigzag nanotubes. | |
| - Semi-Analytical FEM for Composite Beam Delamination: Decomposed the problem into a basic loading state without delamination and an additional free state with delamination. In the length direction, applied analytical solution, and in the thickness direction, used traditional FEM. Compared the result with that obtained from ANSYS using traditional FEM. Mathematica was used. |
