Extension of the parallel Sparse Matrix Vector Product (SpMV) for the implicit coupling of PDEs on non-matching meshes
(Elsevier, 2018-09-15)
Article.
Accés obert
Article.
Accés obert
The Sparse Matrix Vector Product (SpMV) is one of the main operations of iterative solvers, and, in a parallel context, it is also the siege of point-to-point communications between the neighboring MPI processes. The ...
Study protocol: MyoFit46—the cardiac sub-study of the MRC National Survey of Health and Development
(BioMed Central (BMC), 2022-04)

Background
The life course accumulation of overt and subclinical myocardial dysfunction contributes to older age mortality, frailty, disability and loss of independence. The Medical Research Council National Survey of ...
Alya: Computational Solid Mechanics for Supercomputers
(Springer, 2014-08-13)
Article.
Accés obert
Article.
Accés obert
While solid mechanics codes are now conventional tools both in industry and research, the increasingly more exigent requirements of both sectors are fuelling the need for more computational power and more advanced algorithms. ...
Fully-Coupled Electromechanical Simulations of the LV Dog Anatomy Using HPC: Model Testing and Verification
(Springer, 2015-01-01)
Capítol de llibre.
Accés obert
Capítol de llibre.
Accés obert
Verification of electro-mechanic models of the heart require a good amount of reliable, high resolution, thorough in-vivo measurements. The detail of the mathematical models used to create simulations of the heart beat ...
A parallel finite-element method for three-dimensional controlled-source electromagnetic forward modelling
(Wiley-Blackwell, 2013-02-18)
Article.
Accés obert
Article.
Accés obert
We present a nodal finite-element method that can be used to compute in parallel highly accurate solutions for 3-D controlled-source electromagnetic forward modeling problems in anisotropic media. Secondary coupled-potential ...
Parallel Implementation of Domain Composition Methods
(Saxe-Coburg Publications, 2015-04)
Capítol de llibre.
Accés obert
Capítol de llibre.
Accés obert
Domain composition methods (DCM) consist of obtaining a solution to a problem on a domain, from the formulations of the same problem expressed on various subdomains. These methods have therefore the oppostive objective to ...
MPI+X: task-based parallelization and dynamic load balance of finite element assembly
(Taylor & Francis, 2018)
Article.
Accés obert
Article.
Accés obert
The main computing tasks of a finite element code(FE) for solving partial differential equations (PDE's)
are the algebraic system assembly and the iterative solver. This work focuses on the first task, in the context
of ...
A Review of Element-Based Galerkin Methods for Numerical Weather Prediction: Finite Elements, Spectral Elements, and Discontinuous Galerkin
(Springer, 2015-05-19)
Article.
Accés obert
Article.
Accés obert
Numerical weather prediction (NWP) is in a period of transition. As resolutions increase, global models are moving towards fully nonhydrostatic dynamical cores, with the local and global models using the same governing ...
Evaluating the roles of detailed endocardial structures on right ventricular haemodynamics by means of CFD simulations
(Wiley, 2018-09)
Accés obert
Accés obert
Computational modelling plays an important role in right ventricular (RV) haemodynamic analysis. However, current approaches use smoothed ventricular anatomies. The aim of this study is to characterise RV haemodynamics ...
