Last Friday, Dr John M. Tyler of Louisiana State University gave us a very nice seminar on high performance computing research.

At first, Dr Tyler introduced many simulation materials for scientific computing. Then he present some of the name of his graduate student who do tha same research with him.

Then Dr Tyler introduced the subject of long range R & D. In the goal, he pointed out the two related areas: the potential application and the characteristic of the real world problem. The emphesis of the subject included: "clean" solution, successful simulation, and the finite-element method. The current focus is the simulation of well-block from boast. Then Dr Tyler present the equations of the two phases flow. The numeric solutions include Galerkin's method of weighted residuals.

The adaptive spatial discretilization includes the small elements in regions of activity and large elements in "quiet" region. Testing of model is the Hebert experiment with well, water, and constant water pressure.

Then Dr Tyler presented the dynamic adaptive grids in 2D and 3D finite element. The 3D grid elements at 8 corners and the center of the top face was refined 3 levels.

The Eugene Island simulation includes parallel frontal solver, and MIMD clusters, and etc. Dr Tyler then show some figures of the Eugene Island simulation with mesh (the assighnment of element to processors), and the result curves for well 1 and well 2. The results show that the simulation is fine.

Then Dr Tyler presented the confined disposal facility (CDF) which includes the model to help understanding, the typical dike section of Chicago, and grid generation. Then he introduced the Bourgoyne experiment and the future direction.

At last, Dr Tyler presented subject of image compression model.
