    Purpose: The purpose of this paper is to highlight the possibilities of a novel Lagrangian formulation in dealing with the solution of the incompressible Navier-Stokes equations with very large time steps. Design/meth ...
  • An explicit/implicit Runge–Kutta-based PFEM model for the simulation of thermally coupled incompressible flows 

    Martí, Julio Marcelo; Ryzhakov, Pavel (Springer, 2019-02)
    Article
    Restricted access - publisher's policy
    A semi-explicit Lagrangian scheme for the simulation of thermally coupled incompressible flow problems is presented. The model relies on combining an explicit multi-step solver for the momentum equation with an implicit ...
  • An improved enrichment method for weak discontinuities for thermal problems 

    Martí, Julio Marcelo; Ortega, Ernesto; Idelsohn Barg, Sergio Rodolfo (2017-07)
    Article

    The purpose of this paper is to propose a new elemental enrichment technique to improve the accuracy of the simulations of thermal problems containing weak discontinuities. Design/methodology/approach - The enrichment is ...
  • A semi-explicit multi-step method for solving incompressible navier-stokes equations 

    Ryzhakov, Pavel; Martí, Julio Marcelo (Multidisciplinary Digital Publishing Institute, 2018-01)
    Article
    Open Access
    The fractional step method is a technique that results in a computationally-efficient implementation of Navier–Stokes solvers. In the finite element-based models, it is often applied in conjunction with implicit time ...
