Decoupling mixed finite elements on hierarchical triangular grids for parabolic problems
Arrarás Ventura, Andrés
; Portero Egea, Laura (Elsevier, 2018)
Artículo / Artikulua 
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 ; Portero Egea, Laura (Elsevier, 2015)
Artículo / Artikulua
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 ; Hout, K. J. in ’t; Hundsdorfer, W.; Portero Egea, Laura (Springer, 2017)
Artículo / Artikulua
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, ...
