Scientific Computation and Visualisation

The interests of the group cover a wide range of numerical algorithms, software and visualisation systems. Particular emphasis is placed on the use of adaptivity to compute reliable solutions, parallelism for efficiency and visualisation to provide physical insight inareas such as medical imaging and computational fluid dynamics. Specific areas include numerical analysis and the solution of partial and ordinary differential equations, optimisation methods, shape preserving interpolation and volume visualisation. Many numerical applications are in the area of Computational Fluid Dynamics through the interdisciplinary CFD Centre at Leeds. A particular interest is the design of new visualisation systems, and the extension of the current family of systems such as IRIS Explorer, to encompass the computational and data management aspects of scientific problem solving.
