IncompressibleNavierStokes

Stable Dev Build Status Coverage Aqua QA DOI Downloads Downloads

This package implements energy-conserving solvers for the incompressible Navier-Stokes equations on a staggered Cartesian grid. It is based on the Matlab package INS2D/INS3D. The simulations can be run on the single/multithreaded CPUs or Nvidia GPUs.

Installation

To install IncompressibleNavierStokes, open up a Julia-REPL, type ] to get into Pkg-mode, and type:

julia-repl (v1.10) pkg> add IncompressibleNavierStokes

which will install the package and all dependencies to your local environment. Note that IncompressibleNavierStokes requires Julia version 1.9 or above.

See the Documentation for examples of some typical workflows. More examples can be found in the examples directory.

Source code for paper

See this repository for the source code used in the paper Discretize first, filter next: learning divergence-consistent closure models for large-eddy simulation.

Gallery

The velocity and pressure fields may be visualized in a live session using Makie. Alternatively, ParaView may be used, after exporting individual snapshot files using the save_vtk function, or the full time series using the VTKWriter processor.

Demo

Make sure to have the GLMakie and IncompressibleNavierStokes installed:

julia using Pkg Pkg.add(["GLMakie", "IncompressibleNavierStokes"])

Then run run the following code to make a short animation:

```julia using GLMakie using IncompressibleNavierStokes

Setup

setup = Setup( x = (tanhgrid(0.0, 2.0, 200, 1.2), tanhgrid(0.0, 1.0, 100, 1.2)), boundaryconditions = ((DirichletBC(), DirichletBC()), (DirichletBC(), DirichletBC())), temperature = temperatureequation(; Pr = 0.71, Ra = 1e7, Ge = 1.0, boundary_conditions = ( (SymmetricBC(), SymmetricBC()), (DirichletBC(1.0), DirichletBC(0.0)), ), ), )

Solve equation

solveunsteady(; setup, ustart = velocityfield(setup, (dim, x, y) -> zero(x)), tempstart = temperaturefield(setup, (x, y) -> 1 / 2 + sinpi(30 * x) / 100), tlims = (0.0, 30.0), t = 0.02, processors = (; anim = animator(; setup, path = "temperature.mp4", fieldname = :temperature, colorrange = (0.0, 1.0), size = (900, 500), colormap = :seabornicefire_gradient, nupdate = 5, ), ), ) ```
