Adaptive timestepping for conservation laws via adjoint error representation
… to the 2D Euler equations, where we couple the adaptive time-stepping with spatial adaptation. For the spatial adaptation, we use a multiscale-based strategy developed by Müller [38], which we combine with the time adaptive method. The combined space-time adaptive method provides an efficient …

A phase-field study of ternary multiphase microstructures
… semi-implicit Runge-Kutta time integrator and adaptive timestepping, resulting in two orders of magnitude improvement in efficiency. A diffusion-limited growth instability in multiphase thin-film systems was discovered, highlighting how ternary systems differ from binary systems, and intricate …

The role of adaptivity in a numerical method for the Cox-Ingersoll-Ross model
We demonstrate the effectiveness of an adaptive explicit Euler method for the approximate solution of the Cox-Ingersoll-Ross model. This relies on a class of path-bounded timestepping strategies which work by reducing the stepsize as solutions approach a neighbourhood of zero. The method is hybrid …
