    Numerical simulations using LES with tabulated chemistry based on the Flamelet Generated Manifold (FGM) method are conducted with the aim to understand the influence of mixture stratification on the flame dynamics on a ...
  • Refining simplex points for scalable estimation of the Lebesgue constant 

    Jiménez Ramos, Albert; Gargallo Peiró, Abel; Roca Navarro, Francisco Javier (Springer, 2023)
    Conference report
    Restricted access - publisher's policy
    To estimate the Lebesgue constant, we propose a point refinement method on the d-dimensional simplex. The proposed method features a smooth gradation of the point resolution, neighbor queries based on neighbor-aware ...
  • Estimating the Number of Similarity Classes for Marked Bisection in General Dimensions 

    Belda Ferrín, Guillem; Ruiz-Gironés, Eloi; Roca, Xevi (Springer, 2024)
    Conference lecture
    Restricted access - publisher's policy
    To measure the stability of a marked bisection method, we estimate in general dimensions an upper bound of the number of generated similarity classes. Moreover, to understand the cyclic similarity structure, we estimate ...
