DEPARTMENT OF COMPUTER SCIENCE UNIVERSITY OF WATERLOO SEMINAR ACTIVITIES COMPUTER GRAPHICS/SCIENTIFIC COMPUTATION SEMINAR - Thursday, October 27, 1988 Dr. Jiachang Sun, Minnesota Supercomputer Institute and Computing Center, Academia Sinica, will speak on ``B- Spline Finite Element Methods''. TIME: 4:00 PM ROOM: DC 1304 ABSTRACT This talk will introduce the current state of development of computations based on bivariate polynomials and piecewise polynomials over triangular partitions. As an application we will show how to construct comforming bivariate cubic B-spline elements for solving the following bending problem with clamped plates 2 Delta W = f/D in R, W = partial W/partial n = 0 Gamma Gamma on Gamma here R is a convex domain which can completely divided with a three-direction mesh, and Gamma is the boundary. The approximation has been shown to have order O(h) in 2 the space H (O). Numerical examples will be given. 0
