    • Decoupling mixed finite elements on hierarchical triangular grids for parabolic problems 

      Arrarás Ventura, Andrés Upna Orcid; Portero Egea, Laura Upna Orcid (Elsevier, 2018)   Artículo / Artikulua  OpenAccess
      In this paper, we propose a numerical method for the solution of time-dependent flow problems in mixed form. Such problems can be efficiently approximated on hierarchical grids, obtained from an unstructured coarse ...
    • Improved accuracy for time-splitting methods for the numerical solution of parabolic equations 

      Arrarás Ventura, Andrés Upna Orcid; Portero Egea, Laura Upna Orcid (Elsevier, 2015)   Artículo / Artikulua  OpenAccess
      In this work, we study time-splitting strategies for the numerical approximation of evolutionary reaction–diffusion problems. In particular, we formulate a family of domain decomposition splitting methods that overcomes ...
    • Modified Douglas splitting methods for reaction–diffusion equations 

      Arrarás Ventura, Andrés Upna Orcid; Hout, K. J. in ’t; Hundsdorfer, W.; Portero Egea, Laura Upna Orcid (Springer, 2017)   Artículo / Artikulua  OpenAccess
      We present modifications of the second-order Douglas stabilizing corrections method, which is a splitting method based on the implicit trapezoidal rule. Inclusion of an explicit term in a forward Euler way is straightforward, ...
