Efficient mass and stiffness matrix assembly via weighted Gaussian quadrature rules for B-splines 

Barton, M.Autoridad BCAM; Puzyrev, V.; Deng, Q.; Calo, V.M. (2019-12-14)
Calabr{\`o} et al. [10] changed the paradigm of the mass and stiffness computation from the traditional element-wise assembly to a row-wise concept, showing that the latter one offers integration that may be orders of ...

5-axis double-flank CNC machining of spiral bevel gears via custom-shaped milling tools -- Part I: modeling and simulation 

Bo, P.; Gonzalez, H.; Calleja, A.; Lopez de Lacalle, N.; Barton, M.Autoridad BCAM (2019-11-20)
A new category of 5-axis flank computer numerically controlled (CNC) machining, called \emph{double-flank}, is presented. Instead of using a predefined set of milling tools, we use the shape of the milling tool as a free ...

On the application of isogeometric finite volume method in numerical analysis of wet-steam flow through turbine cascades 

Hashemian, A.Autoridad BCAM; Lakzian, E.; Ebrahimi-Fizik, A. (2019-10)
The isogeometric finite volume analysis is utilized in this research to numerically simulate the two-dimensional viscous wet-steam flow between stationary cascades of a steam turbine for the first time. In this approach, ...

Explicit-in-Time Variational Formulations for Goal-Oriented Adaptivity 

Muñoz-Matute, J.Autoridad BCAM (2019-10)
Goal-Oriented Adaptivity (GOA) is a powerful tool to accurately approximate physically relevant features of the solution of Partial Differential Equations (PDEs). It delivers optimal grids to solve challenging engineering ...

Reducing variability in the cost of energy of ocean energy arrays 

Topper, M.B.R.; Nava, V.Autoridad BCAM; Collin, A.J.; Bould, D.; Ferri, F.; Olson, S.S.; Dallmann, A.R.; Roberts, J.D.; Ruiz Minguela, P.; Jeffrey, H.F. (2019-09)
Variability in the predicted cost of energy of an ocean energy converter array is more substantial than for other forms of energy generation, due to the combined stochastic action of weather conditions and failures. If the ...
