Research Projects:

1. An efficient and accurate solver for the convection-diffusion equation arising from flow simulations developed from September 1998 - Present.

· The standard Galerkin FEM discretization and various Streamline Diffusion FEM schemes are integrated into the solver.

· Both moving mesh and adaptive mesh refinement are implemented in the solver by utilizing the a posteriori error indicators.

· Robust iterative linear solvers, including preconditioned generalized minimal residual methods, multigrid and algebraic multigrid, are also available for the users.

2. Finite element analysis on the deformation of a lightweight composite space reflector, January 1997 – September 1998.

· Built the geometric model of the reflector from the measurements provided by the manufacturers and generated mesh for FEM computation.

· Designed a data structure that enabled easy configuration of the material property in different parts of the reflector and easy assembling of different parts of the computation meshes of the reflector.

· Investigated the deformation of the reflector by linear finite element analysis using 9-node shell elements based on the assume strain formulation.
