Subdivided linear and curved meshes preserving features of a linear mesh model
(Sandia National Laboratories, 2019)
Conference report
Open AccessTo provide straight-edged and curved piece-wise polynomial meshes that target a unique smooth geometry while preserving the sharp features and smooth regions of the model, we propose a new fast curving method based on ... -
OpenFOAM computational fluid dynamics simulations of thermal wind generation in mountain/valley configurations
(2021)
Conference report
Open AccessThermal winds appear in mountainous areas and valleys due to temperature gradients caused by the buoyancy effects associated with the diurnal heating-cooling cycle of the lower atmosphere. These winds develop over complex ... -
Local bisection for conformal refinement of unstructured 4D simplicial meshes
(Springer, 2018)
Conference report
Open AccessWe present a conformal bisection procedure for local refinement of 4D unstructured simplicial meshes with bounded minimum shape quality. Specifically, we propose a recursive refine to conformity procedure in two stages, ... -
Defining a stretching and alignment aware quality measure for linear and curved 2D meshes
(Springer, 2018)
Conference report
Open AccessWe define a regularized shape distortion (quality) measure for curved high-order 2D elements on a Riemannian plane. To this end, we measure the deviation of a given 2D element, straight-sided or curved, from the stretching ... -
A high order finite element formulation for the simulation of 3D Magneto-Mechanical problems with application to MRI scanners
(2019)
Conference report
Restricted access - publisher's policyTransient magnetic fields generated by the gradient coils in MRI scanners induce eddy currents in their conducting components, which lead to vibrations, imaging artefacts, noise and the dissipation of heat. Heat dissipation ... -
Including magnetotelluric data into multi-observable probabilistic inversion: implications for the physical state and water content of the continental lithosphereIncluding 3D magnetoteluric data into joint probabilistic inversions
(2019)
Conference lecture
Restricted access - publisher's policyMulti-observable probabilistic inversion [e.g. 1,2,3] is providing new insights into the physicochemical structure of the lithosphere and its complex interaction with the underlying convecting upper mantle. Of particular ... -
Transmission Loss formulas for junctions taking into accountin-plane waves
(2019)
Conference report
Open AccessIn the transmission of vibrations through structural junctions at high frequencies,the distribution of energy between wave types con suffer important variations. It means, for example, that incoming energy concentrated in ... -
Application of inverse SEA models to obtain the Coupling LossFactor in structural junctions from numerical simulations
(2019)
Conference report
Open AccessAn inverse SEA procedure that mimics the Experimental SEA (ESEA) is used in order to obtain the Coupling Loss Factor (CLF) of structural junctions. The main differences with respect to ESEA are that: 1) the subsystem ... -
Comparison of continuous and hybridizable discontinuous Galerkin methods in incompressible fluid flow problems
(International Centre for Numerical Methods in Engineering (CIMNE), 2017)
Conference report
Restricted access - publisher's policyA comparison of the computational efficiency between Continuous Galerkin (CG) methods, with Taylor–Hood approximations, and Hybridizable Discontinuous Galerkin (HDG) methods is presented for the solution of the incompressible ... -
Coupling of continuous and HDG methods
(International Centre for Numerical Methods in Engineering (CIMNE), 2018)
Conference report
Open AccessA coupling strategy between hybridizable discontinuous Galerkin (HDG) and continuous Galerkin (CG) methods is proposed in the framework of second-order elliptic operators. The coupled formulation is implemented and its ... -
Classifying granular materials for feeding performance using experimental and numerical techniques
(2018)
Conference report
Restricted access - publisher's policyFlowability of powders and bulk solids is critical for the packaging industry in the selection and design of bulk material handling equipment. Nowadays, a variety of feeder systems are used for dosing operations in bagging ...
