    A stabilized finite element method using a discontinuous level set approach for solving two phase incompressible flows

    No full text
    A numerical method for the simulation of three-dimensional incompressible two-phase flows is presented. The proposed algorithm combines an implicit pressure stabilized finite element method for the solution of incompressible two-phase flow problems with a level set method implemented with a quadrature-free discontinuous Galerkin (DG) method [E. Marchandise, J.-F. Remacle, N. Chevaugeon, A quadrature free discontinuous Galerkin method for the level set equation, Journal of Computational Physics 212 (2006) 338-357]. The use of a fast contouring algorithm [N. Chevaugeon, E. Marchandise, C. Geuzaine, J.-F. Remacle, Efficient visualization of high order finite elements, International Journal for Numerical Methods in Engineering] permits us to localize the interface accurately. By doing so, we can compute the discontinuous integrals without neither introducing an interface thickness nor reinitializing the level set. The capability of the resulting algorithm is demonstrated with "large scale" numerical examples (free surface flows: dam break, sloshing) and "small scale" ones (two phase Poiseuille, Rayleigh-Taylor instability).

    High-Order Mesh Generation for CFD

    No full text
    While a consensus is forming in the computational physics community on the superior efficiency of high-order numerical schemes, it has been shown that linear geometrical discretizations can deprive such schemes from their benefits. The need for curvilinear mesh generation tools is becoming more acute as high-order methods are being brought to the level of practical applications. In this talk, we report on the development of a high-order unstructured mesh generation method based on an unconstrained optimization procedure [1], occasionally supplemented with an analytical technique. As invalid elements often appear when creating high-order meshes, emphasis is put on robustness: the optimization procedure is specifically designed to enforce mesh validity, that is evaluated through the estimation of provably correct bounds for the Jacobian of the elements [2]. The objective function can also account for the distance between the real geometry and the mesh boundary, in order to optimize the geometrical accuracy. Moreover, the method can be used to control the numerical effects of high-order meshes in solvers. The application of the optimization procedure to well-chosen subdomains instead of the whole mesh makes the method computationally affordable. Computation time can further be saved in boundary layer meshes for CFD by aggregating elements by column, which makes it possible to interpolate analytically the boundary curvature into the domain. We will show the benefits of our technique with several high-order meshes built for realistic applications in different fields. [1] T. Toulorge, C. Geuzaine, J.-F. Remacle, and J.
