SANCHEZ-CHAVEZ, H.D.; LOPEZ-ORTIZ, C.A.  and  FLORES-CANO, L.. Generalities on finite element discretization for fractional pressure diffusion equation in the fractal continuum. Rev. mex. fis. [online]. 2019, vol.65, n.3, pp.251-260.  Epub Apr 30, 2020. ISSN 0035-001X.

In this study we explore the application of the novel Fractional Calculus in Fractal Continuum (FCFC), together with the Finite Element Method (FEM), in order to analize explicitly how these differential operators act in the process of discretizing the generalized fractional pressure diffusion equation for a three-dimensional anisotropic continuous fractal flow. The Master Finite Element Equation for arbitrary interpolation functions is obtained. As an example, MFEE for the case of a generic linear tetrahedron in ℝ 3 is shown. Analytic solution for the spatial variables is determined over a canonical tetrahedral finite element in global coordinates.

Keywords : Finite element; fractional calculus in fractal continuum; anisotropic continuous fractal flow; fractional pressure diffusion equation; continuum mechanics.
