    • A pseudo-DNS method for the simulation of incompressible fluid flows with instabilities at different scale 

      Idelsohn Barg, Sergio Rodolfo; Nigro, Norberto; Larreteguy, Axel; Gimenez, Juan Marcelo; Ryzhakov, Pavel (Springer, 2020-01)
      Article
      Accés obert
      In this work, a new model for the analysis of incompressible fluid flows with massive instabilities at different scales is presented. It relies on resolving all the instabilities at all scales without any additional model, ...

    • Elemental enriched spaces for the treatment of weak and strong discontinuous fields 

      Idelsohn Barg, Sergio Rodolfo; Gimenez, Juan Marcelo; Martí, Julio Marcelo; Nigro, Norberto (2017-01)
      Article
      Accés obert
      This paper presents a finite element that incorporates weak, strong and both weak plus strong discontinuities with linear interpolations of the unknown jumps for the modeling of internal interfaces. The new enriched space ...

    • Lagrangian versus Eulerian integration errors 

      Idelsohn Barg, Sergio Rodolfo; Oñate Ibáñez de Navarra, Eugenio; Nigro, Norberto; Becker, Pablo Agustín; Gimenez, Juan Marcelo (2015-08)
      Article
      Accés obert
      The possibility to use a Lagrangian frame to solve problems with large time-steps was successfully explored previously by the authors for the solution of homogeneous incompressible fluids and also for solving multi-fluid ...
