(Universitat Politècnica de Catalunya. CIMNE, 2019)
Article
Open AccessIn this work, the study of smoke fire transportation inside of a subway passenger platform is presented. The study includes a set of numerical simulations to observe the behavior of the smoke inside the platform. Two smoke ... -
A 4-node thin shell element based on co-rotational for laminated composite structures
(Universitat Politècnica de Catalunya. CIMNE, 2018)
Article
Open AccessThe finite formulation of the 4-node thin shell element based on Co-rotational (CR) and Timoshenko's theory was presented for the analysis of laminated composite structures. Based on the Timoshenko's theory the present ... -
A branch-and-cut algorithm for the multidepot rural postman problem
(2018-03)
Article
Open AccessThis paper considers the Multidepot Rural Postman Problem, an extension of the classical Rural Postman Problem in which there are several depots instead of only one. The aim is to construct a minimum cost set of routes ... -
A C0 interior penalty Finite Element Method for flexoelectricity
(2021-09)
Article
Open AccessWe propose a C0 Interior Penalty Method (C0-IPM) for the computational modelling of flexoelectricity, with application also to strain gradient elasticity, as a simplified case. Standard high-order C0 finite element ... -
A case study for the assessment of a dynamic passenger ride sharing mobility service
(2017)
Conference report
Restricted access - publisher's policySustainable mobility is not merely a technological question. While automotive technology will be part of the solution, it will also be combined with a paradigm shift from car ownership to vehicle usage, which itself will ... -
A Cellular Automata Model for Integrated Simulation of Land Use and Transport Interactions
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-03-08)
Article
Open AccessCellular automata (CA) models have been used in urban studies for dealing with land use change. Transport and accessibility are arguably the main drivers of urban change and have a direct influence on land use. Land use ... -
A combined rh-adaptive scheme based on domain subdivision. Formulation and linear examples
(Wiley and Sons, 2001-09)
Article
Open AccessAn adaptive scheme is proposed in which the domain is split into two subdomains. One subdomain consists of regions where the discretization is refined with an h-adaptive approach, whereas in the other subdomain node ... -
A comparative study of two compact finite difference methods: standard vs. mimetic
(Sociedad Venezolana de Métodos Numéricos en Ingeniería, 2014)
Conference report
Restricted access - publisher's policyIn this work, we implement two fourth-order compact finite differences (CFD) methods and use them to model wave propagation on a elastic string. The formulation of the first method employs the standard implicit CFD constructed ... -
