UK Consortium on Mesoscale Engineering Sciences (UKCOMES)

Lead Research Organisation: University College London
Department Name: Mechanical Engineering

Abstract

UKCOMES addresses scientific and engineering problems at mesoscales which lie between atomistic and macroscales. Such problems are ubiquitous in, for example, a wide variety of physical, chemical, biological, biomedical, material, pharmaceutical and engineering phenomena and processes. Mesoscale engineering sciences are truly interdisciplinary and cross-cutting, uniting the engineering and science research communities. UKCOMES brings together all the required expertise to make critical theoretical discoveries and translate these new concepts into software that is able to exploit today's and future high-end computing (HEC) developments. The modelling and simulation methodologies are based on non-continuum or discrete approaches, including lattice Boltzmann method (LBM), dissipative particle dynamics (DPD), smoothed particle hydrodynamics (SPH) and coarse-grained molecular dynamics (CG-MD). UKCOMES has been funded by the EPSRC (Grant No. EP/L00030X/1, 01/06/2013 - 31/05/2018) for HEC resources. It has also won an award under the EPSRC Computational Science and Engineering Software Flagship Project Call (EP/P022243/1, 06/2017 - 05/2020, HiLeMMS, £513,863). The expanded UKCOMES will capitalize on its successes to lead the research field in the world and to deliver both academic and end-user impact.

Planned Impact

The research of UKCOMES has a natural alignment with many of EPSRC's priority areas including energy, sustainability, environment engineering, digital economy, healthcare technologies, low-carbon technologies, nanotechnologies, and so on. It also supports the strategic goals of: (a) Software as an Infrastructure of the EPSRC; (b) UK e-infrastructure Strategy for Science and Business of BIS; (c) Shaping Capability, Developing Leaders and Delivering Impact of the EPSRC; and (d) The Royal Academy of Engineering strategy for "Jobs and growth: the importance of engineering skills to the UK economy"

The research will fill a major gap in the understanding and utilization of mesoscale phenomena and processes, and will provide improved modelling tools and the fundamental understanding of mesoscale phenomena to help designers, developers and manufacturers to improve design capabilities and shorten product development cycles, thus benefitting the aeronautical, automotive, chemical, food, manufacturing, pharmaceutical and process industries and strengthening UK's industrial competitiveness overall.

One of the key objectives of UKCOMES is to make LBM more accessible, affordable and capable for industrial applications. By developing open-source codes like DL_MESO and HemeLB, industry can gain access easily without excessive expenses. Already, the current users of DL_MESO work in a wide range of areas that include chemistry, chemical engineering, physics, biology, pharmaceuticals, environmental science, mechanical engineering, materials science, metallurgy and applied mathematics. By extending the technical capabilities further, especially in handling complex geometries and realistic physical parameters, DL_MESO will be much more popular with industrial R & D than it is now. It should also be mentioned that while cutting-edge scientific research using LBM requires HEC, the majority of LBM simulations for industry can be done within hours or at most a couple of days on a standard desktop.

Pilot studies will be conducted jointly with industrial partners Mitsubishi Electric in Livingston, UK and The National Supercomputing Centre (NSC) at Wuxi, China. With Mitsubishi, the capabilities of DL_MESO for HVAC applications will be explored for both prediction and design optimization. With NSC, the main purpose is to test the consortium community codes on new supercomputing architectures so that a wide range of end-users can benefit from these codes. Fund is requested to cover the travel and subsistence as well as other research consumables. The total cost is estimated to be £10,000. Additional funding from the two industrial partners has been secured (see their letters of support).

The project will train one highly skilled postdoc who is directly funded by the grant. More importantly, funding for UKCOMES will help to sustain a research community in the field, in which PhD students and postdocs funded by other sources are trained in a rich and stimulating interdisciplinary environment. By having opportunities to attend technical meetings and workshops, they would also gain vital communication and presentation skills as well as computing skills of HEC. The project will run two open workshops and will invite people from industry and academia to attend. This will provide updated mesoscopic modelling knowledge and new software suites to various end-users.

Title Development and performance of a HemeLB GPU code for human-scale blood flow simulation 
Description In recent years, it has become increasingly common for high performance computers (HPC) to possess some level of heterogeneous architecture - typically in the form of GPU accelerators. In some machines these are isolated within a dedicated partition, whilst in others they are integral to all compute nodes - often with multiple GPUs per node - and provide the majority of a machine's compute performance. In light of this trend, it is becoming essential that codes deployed on HPC are updated to execute on accelerator hardware. In this paper we introduce a GPU implementation of the 3D blood flow simulation code HemeLB that has been developed using CUDA C++. We demonstrate how taking advantage of NVIDIA GPU hardware can achieve significant performance improvements compared to the equivalent CPU only code on which it has been built whilst retaining the excellent strong scaling characteristics that have been repeatedly demonstrated by the CPU version. With HPC positioned on the brink of the exascale era, we use HemeLB as a motivation to provide a discussion on some of the challenges that many users will face when deploying their own applications on upcoming exascale machines.

Title Simulation Files from Red blood cell dynamics in extravascular biological tissues modelled as canonical disordered porous media 
Description The dynamics of blood flow in the smallest vessels and passages of the human body, where the cellular character of blood becomes prominent, plays a dominant role in the transport and exchange of solutes. Recent studies have revealed that the micro-haemodynamics of a vascular network is underpinned by its interconnected structure, and certain structural alterations such as capillary dilation and blockage can substantially change blood flow patterns. However, for extravascular media with disordered microstructure (e.g. the porous intervillous space in the placenta), it remains unclear how the medium's structure affects the haemodynamics. Here, we simulate cellular blood flow in simple models of canonical porous media representative of extravascular biological tissue, with corroborative microfluidic experiments performed for validation purposes. For the media considered here, we observe three main effects: first, the relative apparent viscosity of blood increases with the structural disorder of the medium; second, the presence of red blood cells (RBCs) dynamically alters the flow distribution in the medium; third, symmetry breaking introduced by moderate structural disorder can promote more homogeneous distribution of RBCs. Our findings contribute to a better understanding of the cell-scale haemodynamics that mediates the relationship linking the function of certain biological tissues to their microstructure.

Description Understanding the role of porous electrodes in the performance of redox flow batteries 
Organisation Massachusetts Institute of Technology
Country United States 
Sector Academic/University 
PI Contribution My research team use our advanced 3D pore scale lattice Boltzmann model to simulate transport and multiphase flow, coupled with electrochemical reactions, within various porous electrodes for redox flow batteries. The model provide current and voltage profile across the electrode, and is able to separate the structure effect on concentration overpotential and activation overpotential. The simulations have helped to understand why different electrode materials (Freudenberg paper, SGL paper and carbon cloth) give different performance and provide a guideline as to what structure is desirable for achieving high performance in redox flow batteries.
Collaborator Contribution My partners at MIT test different electrode materials in their redox flow battery set up and provide experimental data to validate the model. Our partners at Imperial College London provide imaging data to input to the model, so that we could perform simulations directly on real porous electrodes, and compare the simulated performance with the experimental measurement, to validate the model.
Impact In this collaboration, we have improved our model to give performance predictions of redox flow batteries that match the experimental measurement. The model is now ready to be taken forward to help design optimal electrode structures. In a first step we examined three electrodes with different porous structures. We revealed that a porous structure with uniform pore size distribution around a dominant pore size peak around 20 micrometer and a small fraction of larger pores is beneficial. We have a joint publication to be published soon with Journal of Power Sources.

Title DL_MESO version 2.7 
Description DL_MESO is a general purpose mesoscale simulation package written in Fortran and C++. It supports both Lattice Boltzmann Equation (LBE) and Dissipative Particle Dynamics (DPD) simulations for a wide range of phenomena. It is supplied with its own Java-based Graphical User Interface (GUI) and is capable of both serial and parallel execution. Version 2.7 was released in December 2018. 
Type Of Technology Software 
Year Produced 2018 
Open Source License? Yes  
Impact DL_MESO is a CCP5 and UKCOMES flagship open-source software project available worldwide to academic and commercial researchers. The existence of this software has led to over 100 publications to date studying a wide range of phenomena (e.g. drug loading and release, self-assembly, membrane proton exchange) at the mesoscale using LBE and DPD modelling techniques. New developments in these mesoscopic methods (e.g. cascaded LBE) have been incorporated into DL_MESO in its role as a community code for UKCOMES, which aids dissemination to the wider academic community. More than 1600 academic licences have been granted for DL_MESO (460 for the previous version), while the codes have also been used in several industrial projects related to computer aided formulation and product manufacturing. 
 
Title HiLeMMS 
Description In this project, we are developing a domain-specific language (DSL) approach for lattice Boltzmann modelling. The purpose is to hide the implementation details from either an end-user or an application developer so that the users can focus on the algorithm and application. The project is split into two phases. In the first phase, we have developed function sequence that will enable the user to combine the provided lattice Boltzmann models (e.g., provided equilibrium functions, boundary conditions and forces terms) to simulate a scientific problem. In the second phase we have proposed and implemented a few key templated objects that can help researchers to write the so-called user-defined function (UDF) and develop their applications easily as well as an experimental python translator for the same purpose. The proposed abstract is released at https://gitlab.com/jpmeng/hilemms, whilst two backend codes (i.e., OPS based and AMReX based) are released at https://github.com/jpmeng/MPLB by DL and https://github.com/otbrown/LAMBReX by EPCC.

Open Source License? Yes  
Impact By developing the high-level abstraction approach, we enable the declarative programming paradigm for the lattice Boltzmann modelling. This will help the communication between domain expert and code developer and ease the code usage. Two backend codes have been publicly released on Github, which can be accessed by the wider community. For the backend code developed at DL, we have attracted a couple of groups to use the code, namely, the State Key Laboratory of Hydraulics and Mountain River Engineering, Sichuan University on environmental research, the University of Edinburgh on additive manufacturing. A group at the University of Durham start to tentatively explore the usage of code. The code had been used for an IROR project of the STFC Hartree Centre.

Title Processing Tools for HemeLB Simulations 
Description This repository contains the pre-processing and post-processing tools used in the simulations described in the referenced paper. Here FiveExit and ProfundaFemoris2 refer to the five-outlets model and the profunda femoris model described in the paper, respectively. The simulation cases studied are listed in the file experiments.csv in the corresponding sub-folders. For example, FiveExit_coarse refers to the simulations using the coarse grid and the five-outlets model. The simulations described in the paper were performed using HemePure, a HemeLB version with improved memory, compilation and scaling. The input files for these simulations were generated by the Python script writeInput.py. This script imports MyModules/InputOutput.py and reads experiments.csv and input_VfWKf.xml in the corresponding sub-folders, where the constant parameters for each simulation domain are provided in const_param.csv. To use this script, execute the command "python writeInput.py" with Python of version 3.6 or above. The outputs of HemeLB were first processed using paraviewPreprocess.sh to obtain human-readable outputs. These outputs were analysed using verification.py. The figures in the paper and its supplementary figures were generated using analysis.py.
