    Solving a chemotaxis-haptotaxis system in 2D using Generalized Finite Difference Method
    (ScienceDirect, 2020-05-27) Benito Muñoz, Juan J.; García Hernández, Miguel Ángel; Gavete Corvinos, Luis Antonio; Negreanu, Mihaela; Ureña, Francisco; Vargas Ureña, Antonio Manuel; https://orcid.org/0000-0002-9092-9619; https://orcid.org/0000-0001-6581-5671; https://orcid.org/0000-0003-0533-3464
    We study a mathematical model of cancer cell invasion of tissue (extracellular matrix) consisting of a system of reaction-diffusion-taxis partial differential equations which describes the interactions between cancer cells, the matrix degrading enzyme and the host tissue. We analyze the local stability of the constant equilibrium solutions to the chemotaxis-haptotaxis system, we derive a discretization of the system by means of the Generalized Finite Difference Method (GFDM) and we prove the convergence of the discrete solution to the analytical one. Also, we provide several numerical examples on the applications of this meshless method over regular and irregular domains.

    Numerical solution of a hydrodynamic model with cavitation using finite difference method at arbitrary meshes
    (ScienceDirect, 2024-07-25) García Hernández, Miguel Ángel; Negreanu, Mihaela; Ureña, Francisco; Vargas Ureña, Antonio Manuel; https://orcid.org/0000-0003-0533-3464 View this author’s ORCID profile
    In this paper, we investigate the implementation of the finite difference method on arbitrary meshes in conjunction with a fixed-point algorithm for the lubrication problem of a journal bearing with cavitation, considering the Elrod-Adams model. We establish numerical properties of the generalized finite difference scheme and provide several illustrative examples.
