MARIE CURIE GRANT AGREEMENT NUMBER859836
The Early Stage Researcher (ESR) will be hired for two 18 months periods as part of the MeDiTATe project, which is funded through the H2020 program: Marie Skłodowska-Curie Actions (MSCA) Innovative Training Networks – European Industrial Doctorate. The ESR will be enrolled in the PhD programme of the School of Mechanical Engineering of the National Technical University of Athens (NTUA), Greece. The ESR individual project will be realized at: (a) the NTUA (Parallel CFD & Optimization Unit, PCOpt). The PCOpt/NTUA, headed by Prof. K. Giannakoglou has great experience in developing CFD tools, optimization methods (adjoint & evolutionary algorithms) and applying them in single and multi-disciplinary real-world problems (see: http://18.104.22.168/research/); (b) at the ESI Group – Paris (France), in the Scientific Department headed by Prof. F. Chinesta who is a world recognized authority in Model Order Reduction methods. Within this department is also Dr. A. Kamoulakos who has expertise in the numerical structural analysis and associated materials modelling and who will supervise in conjunction with Prof. Chinesta the ESR. A one-month secondment in the Fondazione Toscana G. Monasterio (Italy) is foreseen.
The objective of the ESR is to integrate and use a CFD model to simulate the flow in aneurysms, assuming rigid nonflexible walls with infinite resistance, running on GPU clusters; the NTUA, GPU-enabled, finite-volume URANS code version will be used as the background tool. Modifications will be performed to accommodate varying fluid properties. The ESR will be responsible for (a) processing data from computed tomography (CT), grid generation and post-processing of results for visualization purposes. Emphasis will be given to the memory handling, so as to minimize MPI-based inter-board communications. Next to this, ROM techniques will be examined for the CFD computations and, in particular, the concepts of HyperReduction, POD, PGD and Artificial Neural Networks (contribution by ESI). Studies with Newtonian fluid model and variable viscosity will be carried out. Geometric quantities (aneurysm length, maximum diameters, etc.) and the associated non-dimensional metrics or indices of the aneurysm will be correlated with the hemodynamic loads and the rupture risk. Studies will focus on estimates of the aneurysm rupture risk. The rupture risk will be examined within suitable HiFi arterial wall simulations using the EWK model of the VPS s/w by ESI. An artificial neural network will be created to represent the detailed rupture within a global FE model. By doing so, CFD can improve the understanding of factors determining the origin and progression of aneurysms. Moreover, trained Deep Neural Networks will be used to predict the failure points of the arterial wall, the origin and the progress of the aneurysms by avoiding the expensive CFD process.
Applicants should send CV, cover letter, BSc and MSc degrees, and letters of recommendation to all the following recipients: email@example.com and firstname.lastname@example.org with subject 'ESR04 for MeDiTATe'.
The selected candidate will receive a salary in accordance with the MSCA regulations for ESR. The gross salary includes a living allowance (€3,270 per month, subject to MSCA country correction coefficient, i.e. 88.7% for Greece and 115.7% for France), a mobility allowance (€600 per month), and a family allowance (€500 per month, if the researcher has family by the date of recruitment, regardless of whether the family will move with the researcher or not). The guaranteed funding is for 36 months (i.e. EC funding).
Applicants can be of any nationality and must hold a Master of Science degree (or equivalent) in engineering. They need to fully respect both eligibility criteria (to be demonstrated in the Europass CV): (a) Early-Stage Researchers (ESRs) must, at the date of recruitment by the beneficiary, be in the first four years (full-time equivalent research experience) of their research careers and have not been awarded a doctoral degree. (b) Conditions of international mobility of researchers: Researchers are required to undertake trans-national mobility (i.e. move from one country to another) when taking up the appointment. At the time of selection by the host organization, researchers must not have resided or carried out their main activity (work, studies, etc.) in Greece for more than 12 months in the 3 years immediately prior to their recruitment. Short stays, such as holidays, are not taken into account.
REQUIRED EDUCATION LEVELEngineering: Master Degree or equivalent
Candidates with background in Fluid Mechanics, Computational Fluid Mechanics (primarily) and Computational Structural Mechanics (secondarily) background should apply for this position. Good programming skills (FORTRAN, C++, Python and optionally CUDA) are needed. Some background in Artificial/Computational Intelligence techniques is welcome. Flexibility in the use of open source and proprietary computer aided engineering software. Motivation and interest in Fluid Mechanics, Multi-physics, Biomedical engineering and Artificial Intelligence is preferable. Excellent knowledge of written and spoken English is required.
