Philipp Frauenfelder, Seminar for Applied Mathematics, Federal Institute of Technology (ETH), Zurich TICAM Seminar: "Anisotropic h and p refinement for conforming FEM in 3D" |
The talk will show how we define assembling of global basis functions of FE spaces on regular and irregular meshes in 3D using so called S and T matrices. The method shown does not depend on the spatial dimension or regularity of the mesh and is also applicable to DGFEM or BEM. The mathematical setting which is presented has been implemented in a C++ code called Concepts. The implementation is fully anisotropic (in h and p). Some algorithms involved are explained. The results show the expected exponential convergence for different problems. The work has been done in collaboration with Dr. Christian Lage (372 Funston Avenue, San Fransisco, CA 94118, cl@numiracle.com), and Prof. Christoph Schwab (SAM, ETH, schwab@math.ethz.ch). |

Prof. Hong-Kai Zhao, Dept. of Mathematics, UC Irvine TICAM Seminar: "Computer Visualization using Partial Differential Equations and Implicit Surfaces" |
I will present mathematical formulations and efficient numerical algorithms for the construction, deformation and operation of implicit surfaces using variational methods and partial differential equations. In particular I will discuss surface resonctruction from unorganized data points using distance contours and minimal surfaces and solving partial differential equations on moving interfaces. |
