When computing numerical approximations to problems with smooth solutions using regular grids, the error can have additional structure. The historical example of the Euler-McLaurin formula for the approximation of integrals with the trapezoidal rule...

Implicit time stepping applied to discretized incompressible fluid flow problems results in discrete Stokes-like (saddle-point, KKT) problems. There is a class of so-called Projection Methods in which these Stokes-like problems are efficiently...

A computational framework is presented for materials science models that come from energy gradient flows that lead to the evolution of structure involving two or more phases. The models are considered in periodic cells and standard Fourier spectral...

Two electrochemical systems are described: a small scale, methanol fuel cell and an electrodialysis system to process waste water from oil and gas production. The second is the subject of current work, so it is likely that only preliminary results...

The SFU Mathematics Department invites undergraduate and graduate research students to participate in the 2015 SFU Symposium on Mathematics and Computation Poster Competition. Posters will be judged in two catergories - graduate and undergraduate -...

I am working with colleagues on several projects modelling Lithium Ion batteries. Experimental results are fit to simple models of performance and "State of Health", a vaguely defined measure of the change of battery characteristics with use and age...

Adaptive time stepping methods for meta-stable dynamics of the Allen Cahn and Cahn Hilliard equations are investigated in the spatially continuous, semi-discrete setting. Predicted behaviour of the number of time steps with specified local error...
