Fellowship in Digital Engineering for Fusion Energy

In March 2021, The University of Manchester signed a 10 year collaboration agreement with the UKAEA, resulting in a £15M investment for two new research groups; Digital Engineering and Tritium. I lead the Digital Engineering group. The aim is to build a virtual garage where engineers can try out new designs for fusion reactors more quickly than building full-scale prototypes.

Call for Papers: Special Issue on Advances in Integrated Digital Engineering Applications

Dear Colleagues,

I'm current guest editor on a Special Issue of the MDPI Journal of Applied Sciences. This is a journal with an impact factor of 2.474.

The aim of this Special Issue is to explore the re-engineering of engineering through the integration of advanced digital technologies. Research papers or case studies involving any discipline of engineering are welcome. Topics may include, but are not limited to, the following:

PhD in Fusion Energy

Just a short note before the weekend to let you know that I am offering 4 year PhD topics in advanced modelling & simulation starting in September via the Nuclear Fusion doctoral training network.  One of the topics is to combine the cellular automata finite element method with uncertainty quantification to predict the lifetime of neutron irradiated components in fusion reactors. The deadline for applications is the end of next week. Studentships are available for UK/EU students.

Use of Gaming Technology to Bring Bridge Inspection to the Office

Good afternoon,

We recently published a paper using VR that might be of interest:

Muhammad Omer, Lee Margetts, Mojgan Hadi Mosleh, Sam Hewitt & Muhammad Parwaiz (2019) Use of gaming technology to bring bridge inspection to the office, Structure and Infrastructure Engineering, DOI: 10.1080/15732479.2019.1615962

Building a Digital Wind Farm

We've recently published an extensive review of the state-of-the-art in modelling and simulation for wind energy. The paper is open access for a limited time and can be found online at the link below.

Yield behaviour of trabecular bone

A recently published paper  "Evaluating the macroscopic yield behaviour of trabecular bone using a nonlinear homogenisation approach" links the micromechanics of bone to its macroscopic behaviour. The paper may be of interest to colleagues on this forum. The abstract is provided below.

Abstract:

Summer School - HPC for Engineering Simulation

The STFC Hartree Centre (in Warrington, UK - located between Manchester & Liverpool) is running 4 high performance computing summer schools from June to July 2016. They are primarily aimed at PhD students and postdoctoral researchers, but are also open to academics and industry at no extra cost. The tuition fees are subsidised by STFC and each week only costs £150. There is a 1 week school on each of the following topics:

PhD Vacancy: UK Centre for Doctoral Training in Fusion Energy

I am currently looking to fill an open PhD position in a project titled:

Advanced Virtual Design of 3D Printed Fusion Reactor Components

This is to continue recent work that uses X-ray tomography, high performance computing and finite element analysis to design the plasma facing wall of the ITER reactor. Recent related publications can be found below:

PhD in Biomaterials for Aerospace Composites

Applications are invited for a fully funded PhD studentship at the University of Manchester to help develop the next generation of simulation tools. These will be used to evaluate the structural integrity of novel aerospace composites under a wide range of operational conditions.

PhD Positions in Advanced Virtual Prototyping at the University of Manchester

I am currently recruiting new PhD students to join my research group at The School of Mechanical, Aerospace and Civil Engineering at the University of Manchester. The core focus of the group is advanced computing for engineering simulation. My research interests centre on extreme scale parallel computing, cloud computing and virtual reality simulation platforms, applied to scientific and engineering problems involving complex processes.

Short Course: Advanced Methods in Computational Fluid Dynamics

Research Software Engineer Fellowship

The UK Engineering and Physical Sciences Research Council (EPSRC) is offering Research Software Engineer (RSE) Fellowships for a period of up to five years. The RSE Fellowship describes exceptional individuals with combined expertise in programming and a solid knowledge of the research environment. The eligibility criteria and details of how to apply can be found on the EPSRC website.

PhD Studentship: "Advanced Virtual Prototyping for Sustainable Energy Generation"

I have an EPSRC CASE PhD Studentship on offer that is co-funded by Alstom PLC.

There are three aims: (i) to couple ParaFEM with OpenFOAM for massively parallel fluid-structure interaction; (ii) to release that code into the community and (iii) to use the new capability to study the performance of "whole" wind farms, insilico. 

Cellular Automata for Multi-scale Fracture

Could cellular automata be used to model mechanisms (for quasi-brittle fracture) that occur at the meso-scale and then feed these mechanisms to a macro-scale finite element model? Is it possible to replace constitutive models with mechanistic models, simulating mechanisms that lead to fracture instead of formulating equations that predict failure? These are typical questions that have motivated my recent collaboration with Dr Anton Shterenlikht at the University of Bristol.

Stochastic Review Paper in Movie Form!

A while ago, I shared news about the recent publication of our review paper titled: "Practical Application of the Stochastic Finite Element Method".  The first author David Arregui-Mena, a PhD student at the University of Manchester, created a YouTube movie which summarises the content of the paper.

For those interested, its worth a watch!

Practical Application of the Stochastic Finite Element Method

If you're interested in stochastic finite element analysis, you might like to know that we've just published a paper that reviews the "practical" application of the method. The paper first outlines the main methods of incorporating uncertainty into engineering computations. It then presents "practical" examples across a range of disciplines of where these methods have been used.

We hope that this paper is a good starting point for those looking to adopt stochastics in their work.

Extinct Kangaroos Couldn't Hop

Another couple of interesting articles to share. Using some "mechanics" principles, researchers have reasoned that 100,000 years ago, kangaroos were too heavy to hop.

A while ago, a different group of researchers published the results of computer modelling (using genetic algorithms) that showed dinosaurs might have hopped and skipped as forms of locomotion! (But only if particularly happy?)

These articles might be good to share with undergraduate engineers for discussion in tutorials. There are issues to discuss with assumptions in both cases. 

Survey of Computing Platforms for Engineering Simulation

How many organisations are using Cloud Computing? Is the use of High Performance Technical Computing in engineering simulation set to grow in the next 5 years? Will Tablet PCs be powerful enough to run my application? What do my peers think?

These are typical questions asked by the engineering simulation community. Wouldn't it be great if we could take a snapshot of the type of computing platform we're using today and also predict where we will be in the next 5 years? 

Cracks found at reactor at Hunterston B nuclear power station

Perhaps some of those on this site have seen the news article on the BBC website yesterday about cracks appearing in the reactor at the Hunterston B nuclear power station. As the article states, cracking in the graphite bricks is predicted and the regulators are happy that the reactor is safe to operate.

Sutured tendon repair; a multi-scale finite element model.

We've recently published an open access journal paper that looks at the mechanics of sutures used to repair severed tendons. A homogenization strategy is used to derive effective elastic properties for tendon fibrils and intracellular matrix. We have found that regions of high stress correlate with the regions of cell death (necrosis) that are sometimes observed in patients.

If this is of interest, please feel free to view the paper here.
