Cross section through a Pecube model of the Bhutan Himalaya from Coutand et al., 2014.
Pecube is a numerical modelling program used to simulate heat transfer in the lithosphere and to predict thermochronometer ages. Pecube uses the finite element method to calculate time-dependent temperatures in 3D including the effects of heat conduction, advection, and production. What is somewhat unique with Pecube is that the surface topography can evolve freely with time and there is a fairly flexible kinematic model built in, which allows users to define fault geometries and slip rates within their model domain. Pecube is open source, and available directly from Jean Braun or through the HUGG GitHub.
