NavierStokes ============ This repository implements via finite element solvers for incompressible Navier-Stokes (iNSE) equations in Arbitrary Lagrangian-Eulerian (ALE) formalism the schemes proposed on [RA20]_. It aims to replicate the energy results shown in the article [RA20]_ for both Monolithic and Chorin-Temam solvers. TeX submissions are added for reference. Solvers ------- Both monolithic solver and a fractional step solver are implemented. * Monolithic solver for the iNSE-ALE problem with linearized convective term and Taylor-Hood (P2/P1) stable finite element space. * Fractional step solver for the iNSE-ALE problem with linealized convective term and P1/P1 finite element space. Chorin-Temam schemes proposed here are described in [RA20]_. Flow model ---------- A rectangle domain is taken with fully Dirichlet homogeneous boundary conditions and non-zero initial velocity profile. Further description of the problem also can be found in the reference. Usage ---------- Since the repository aims to directly reproduce the results of the reference, no configuration files where implemented to further customize the problem. Nevertheless, the solvers are easily modified since its implementation is done via FEniCS [LO12]_. To run the simulations and generate the figures depicted in our article, execute:: python main.py Dependencies ------------ - Python >= 3.5 - FEniCS >= 2019.1.0 Reference ^^^^^^^^^^ ..
