      Commonly, the development of scientific computing software follows a stencilbased approach: the numerical methods and algorithms are introduced into computing systems through stencil data structures and sweeps (i.e. ...
    • From pure conduction to homogeneous isotropic turbulence 

      Alsalti Baldellou, Àdel (Universitat Politècnica de Catalunya, 2019-01)
      Master thesis
      Open Access
      L’objectiu d’aquest treball és estudiar multiples casos relacionats amb la dinàmica de fluids i amb la transferència de calor. Més concretament, sis casos de complexitat creixent han estat abordats des de la perspectiva de ...
    • On Preconditioning Variable Poisson Equation with Extreme Contrasts in the Coefficients 

      Alsalti Baldellou, Àdel; Trias Miquel, Francesc Xavier; Gorobets, Andrei; Oliva Llena, Asensio (International Centre for Numerical Methods in Engineering (CIMNE), 2021)
      Conference report
      Open Access
      It is well known that the solution by means of iterative methods of very ill-conditioned systems leads to very poor convergence rates. In this context, preconditioning becomes crucial in order to modify the spectrum of the ...
