“…Despite the finite volume method (FVM) was originally proposed in the context of hyperbolic systems of conservation laws [26,35], there has been a growing interest towards its application to other physical problems, including the simulation of deformable structures [16,47]. Several robust and efficient implementations of the FVM are available in both open-source and commercial libraries, making it an extremely attractive approach for industrialists.…”

A face-centred finite volume (FCFV) method is proposed for the linear elasticity equation. The FCFV is a mixed hybrid formulation, featuring a system of first-order equations, that defines the unknowns on the faces (edges in two dimensions) of the mesh elements. The symmetry of the stress tensor is strongly enforced using the well-known Voigt notation and the displacement and stress fields inside each cell are obtained element-wise by means of explicit formulas. The resulting FCFV method is robust and locking-free in the nearly incompressible limit. Numerical experiments in two and three dimensions show optimal convergence of the displacement and the stress fields without any reconstruction. Moreover, the accuracy of the FCFV method is not sensitive to mesh distortion and stretching. Classical benchmark tests including Kirch's plate and Cook's membrane problems in two dimensions as well as three dimensional problems involving shear phenomenons, pressurised thin shells and complex geometries are presented to show the capability and potential of the proposed methodology.

“…It is interesting to realize that the widely adopted finite-volume formulation of Navier-Stokes equations in integral form via a control volume formulation was first formerly derived by Rizzi and Inouye [8]. The balancing of outward normal vector flux components across the control surface between adjacent control volumes becomes the only constraint to the flux vector splitting technique.…”

A narrative of landmarks in computational fluid dynamics (CFD) is presented to highlight the cornerstone achievements. Illuminating accomplishments starting from the very beginning of the coherent development until the most recent progress will be elucidated over the span over more than six decades. Meanwhile, the cuttingedge scientific innovations will also be discussed for their lasting impacts to fluid dynamics and the physics-based modeling and simulation discipline. To traverse such a vast domain over time by a single presentation, numerous and excellent contributions to CFD will be unavoidably overlooked. Nevertheless it is my ardent hope that the present discussion will be able to reaffirm excellence in research and to identify new frontiers for scientific research. Especially, the challenges to future innovations will also be delineated to recommend for potential and fertile research areas for the modeling and simulation science.

Curriculum vitae 157 List of publications and presentations 159 My research work within my Ph.D. started with the project AMEDEO enabling me to meet and exchange with great people, visit many research institutes and access valuable training all over the journey. For that, I am very grateful to my supervisor Dr. Tom Verstraete who believed on my small but growing GPU expertise back on 2013. Tom has done a fantastic supervising work with me by first giving me the freedom to act in my research but then closely checking my results. Moreover, I would like to thank Juliet Jopson for successfully coordinating the AMEDEO project and making the administration part much easier for all research fellows within the project. I would like also to thank Prof. Harvey Thomson for offering me a secondment within his team at the University of Leeds. During the short stay, I cooperated with Nicolas Delbosc from whom I learned so much about GPU performance assessment. I am very grateful to you Nic. I am thankful to all of AMEDEO people and a special thank to Dr. Roeland de Breuker for putting me in contact with Prof. Kees Vuik who later become my Ph.D. promoter. Prof. Vuik knows how to get a student fully motivated and prepared for the challenges within a Ph.D. project. You name a software library or a research facility and he would surely know someone to contact to make the stuff happen that you asked for (e.g. DAS-5, SURFsara, Paralution). For all the time and the effort you invested in my project I am really thankful. I would like also to thank the graduate school at TU Delft for the enriching courses and the possibility they bring to meet other Ph.D. students and exchange about ideas, challenges, views, fears, and ambitions. I would like to thank Deborah Dongor for helping me through the process of being an external Ph.D. student. My work would not have reached the maturity it has now without the constant support of the people of the TU department in VKI. My supervisor Tom and Prof. Tony Arts were always supportive when it comes to attending conferences and presenting my work. I owe a lot of what I learned during these last years to my colleague Lasse Müller. Besides the valuable discussions he provided me with the CPU version of the CFD simulation, the base of all my work. I am grateful to my colleague Christopher Chahine who taught me a lot of practical knowledge in design optimization. I would like to thank Roberto with whom I cooperated the last months and learned a lot. Eager to continue the collaboration. For the rest of the TU group I xi xii hope we will renew our biweekly department meeting to continue exchanging about our latest results. I would like to thank all the computer center staff here at VKI and also Christelle and Evelyne for supporting my numerous requests for papers and documentation. I am thankful to the VKI administration and especially to Dirk who made all administrative procedures so easy for me at the beginning of my Ph.D. and after him, Simone took over and facilitated all the paper work for me. I would ...
