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.

HemeLB: cardiovascular modelling and simulation in UKCOMES, 29-30 May 2019

Publication date:

UKCOMES are hosting a meeting on "HemeLB: cardiovascular modelling and simulation in UKCOMES" centred around lattice Boltzmann simulations for blood flow. As part of the meeting, researchers at UCL will introduce and demonstrate the use of their HemeLB application and the progress they have made towards simulating the whole arterial tree. There will be talks from other users of HemeLB in addition to alternative LB applications including Palabos and DL_MESO.

2018 UKCOMES International Workshop on Mesoscale Simulation and Modelling The Royal Society

Publication date:

Event: London, UK, 5 – 6 November 2018 


The UK Consortium on Mesoscale Engineering Sciences (UKCOMES) has been established since June 2013 to advance the mesoscale science and engineering through exploitation of world-class high-end computing (HEC). It brings UK and international experts and end-users together to make theoretical advances, develop mesoscopic simulation methods and models, create and maintain community software, disseminate results to both research and end-user communities. UKCOMES ( is part of the UK Research & Innovation strategy to enable and sustain world-class science and engineering research using HEC. It has been supported by EPSRC Grant Nos. EP/L00030X/1 (2013-2018) and EP/R029598/1 (2018-2022). It has been awarded substantial computing resources on national HEC facilities such as ARCHER, with additional software support from CoSeC.

WP G: Multiscale Simulation & Optimisation meeting

Publication date:

A first workshop was held at UCL on December 17th, 2014, attended by 10 representatives of participating consortium groups with presentations by Cranfield (Prof.Savill & Dr. Timos Kipouros); UCL (Prof. Kai Luo & Dr. Daniel Lycett-Brown); Leeds (Dr. Mark Wilson & Nicholas Delbosc); and attendance of Michael Seaton (Daresbury STFC), Rupert Nash (Edinburgh EPCC), Joe O’Connor (Manchester for Revell). Two (international and national) test cases have been established: a baffled micro-reactor configuration for fluid mixing; and a micro-combustor geometry for electrical power generation or thrusters propulsion – URANS, LES and DNS data are already available for these to allow multiscale evaluation against LBM. CPU-based work is underway with the consortium PDRA (Daniel Lycett-Brown) cross-comparing the Southampton/UCL LBM code with the Cranfield one in 2D and then 3D for the micro-reactor case, before moving onto DL_MESO for the micro-combustor mixing case which will then allow the extension to combustion LBM to be explored. A first integration of LBM for micro-fluidic design optimisation within a GPU environment has been achieved at Cranfield; speeding up the process by a factor of more than 50, resulting in a much richer and more detailed design space exploration. The experience gained in porting under CUDA will next be transferred to DL_MESO. The workshop identified the exciting possibilities opened up for topology optimisation and real-time simulation/optimisation, as well as new prospects for deploying LBM for acoustic analyses.
