Mesh Adaptation on the Sphere using Optimal Transport and the Numerical Solution of a Monge-Ampère type Equation
Hilary Weller, Philip Browne, Chris Budd +1
An equation of Monge-Ampère type has, for the first time, been solved numerically on the surface of the sphere in order to generate optimally transported (OT) meshes, equidistribut…

Multi-layer asymptotic solution for wetting fronts in porous media with exponential moisture diffusivity
Christopher J. Budd, John M. Stockie
We study the asymptotic behaviour of sharp front solutions arising from the nonlinear diffusion equation θ_t = (D(θ)θ_x)_x, where the diffusivity is an exponential function D(θ) =…
