Robust Multilevel Preconditioning Techniques for Large Sparse Linear Systems

Schur Complement and Cyclic Reduction

Approximate Inverse Preconditioning for Large Sparse Linear Systems

Preconditioning Techniques for Navier-Stokes Problems

High Order Compact Finite Difference Schemes for Convection Diffusion Equation and the Navier-Stokes Equations
An excellent introduction to high-order compact schemes can be found at Bill Spotz's home page.

Here are some solutions of square driven cavity at Re=10,000. I obtained these solutions in 1995 using the fourth-order compact scheme and I have no idea whether they are correct or not. If you have any comments, please send me an e-mail message.

Personal and Academic Friends


People deserved credits and thanks

The following persons helped me greatly in my early research career by patiently answering my questions and providing me with information and software codes, long before I met them in person. They are, in my opinion, are model researchers, educators, and gentelmen.


Former Advisors, Supervisors, Mentors, and Supporters

The following persons have helped me greatly in my academic career, either as advisors, supervisors, mentors, to point me to the right research directions, or as supporters and friends, to tirelessly show me the right way to be successful in academic life. To them, I have to say: "THANK YOU".
