  • Fluid effects in sand production simulations coupling DEM with CFD 

    Climent Pera, Natalia; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio; O'Sullivan, Catherine (CRC Press Taylor & Francis Group, 2014)
    Conference report

    Sand production around a wellbore is here simulated using a three dimensional numerical model based on Discrete Element Method (DEM) coupled with Computational Fluid Dynamics (CFD). The model is calibrated against a ...
  • Grading evolution and critical state in a discrete numerical model of Fontainebleau sand 

    Ciantia, Matteo Oryem; Arroyo Alvarez de Toledo, Marcos; O'Sullivan, Catherine; Gens Solé, Antonio; Liu, T. (Thomas Telford, 2019-01)
    Article

    Granular materials reach critical states upon shearing. The position and shape of a critical state line (CSL) in the compression plane are important for constitutive models, interpretation of in situ tests and liquefaction ...
  • Multi-scale analysis of cone penetration test (CPT) in a virtual calibration chamber 

    Butlanska, Joanna; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio; O'Sullivan, Catherine (2014-01)
    Article
    Restricted access - publisher's policy
    A virtual calibration chamber was developed using a three-dimensional (3D) discrete element method (DEM) to perform cone penetration tests (CPTs) on a discrete analogue of Ticino sand. The macroscale response of the DEM ...
  • Sensitivity to damping in sand production DEM-CFD coupled simulations 

    Climent Pera, Natalia; Arroyo Alvarez de Toledo, Marcos; O'Sullivan, Catherine; Gens Solé, Antonio (American Institute of Physics Conference Proceeding, 2013)
    Conference report
    Restricted access - publisher's policy
    A three dimensional numerical model based on Discrete Element Method (DEM) and coupled with Computational Fluid Dynamics (CFD) was implemented to simulate sand production. Simulations with no fluid flow conditions and with ...
  • Simulation of the cone penetration test: discrete and continuum approaches 

    Gens Solé, Antonio; Arroyo Alvarez de Toledo, Marcos; Butlanska, Joanna; Monforte Vila, Lluís; Carbonell, J.M.; Ciantia, Matteo; O'Sullivan, Catherine (Australian Geomechanics Society, 2016)
    Conference report

    The paper presents the modelling of the cone penetration test using two procedures: a discrete approach and a continuum approach. The discrete approach is based on the Discrete Element Method where a granular material is ...
