Subset of a wild-type P6 retinal plexus used to reconstruct one of our retinal blood flow models, namely P6A model. The original microscope image is segmented and the network skeleton and segment radii are computed. Based on these values, a three-dimensional volume is reconstructed assuming vessels of piecewise constant radius. (a) Original image. (b) Segmented image. (c) Reconstructed surface. Reproduced from [Bernabeu et al., Journal of the Royal Society Interface, 2014].


Rayleigh-Bénard natural heat convection between cold and hot plates, using additional lattice for heat flows and Boussinesq approximation to couple temperature and fluid flow. Temperature indicated by colour field, fluid flow by velocity streamlines. Included as a demo with DL_MESO.

Prof Peter Coveney Led New EU Project VECMA

12 November 2018

Event Date: June 2018

Professor Peter Coveney has been leading an EU project entitled “Verified Exascale Computing for Multiscale Applications (VECMA)”. The project was awarded €3,999,478 in total, of which the UK partners’ value was €1,763,555. Nine partner organisations in the EU are involved in the 3-year project starting from 15/06/2018.

The aim of the VECMA project is to enable a diverse set of multiscale, multiphysics applications to run on current multi-petascale computers and emerging exascale environments with high fidelity. Simulations are meant to be certifiable as validated (V), verified (V) and equipped with uncertainty quantification (UQ) by tight error bars such that they may be relied upon for making important decisions in all the domains of concern. Examples of applications include fusion, advanced materials, climate and migration, drug discovery and personalised medicine.
