ELP: Finding ALE Code for 1D/2D/3D FV, FD or FE

[hoomanya]

Hi,

I am looking for an example of an ALE code for 1Dor 2D or 3D.It doesn't matter if it is in an FV, FD or FE code. I just need to see how the mesh velocity and the velocity of the fluid are dealt with in the code and how it works generally.

I looked at previous threads and saw the link to the Peric codes:
ftp://ftp.springer.de/pub/technik/peric/

I looked there but couldn't find anything. Does anyone know if ALE is included there and if so what is the name of the file. Or if you have any other source codes I would also appreciate it very much.

Thanks,

H

i there,

Thank you for your interest in ALE codes! ALE stands for Arbitrary Lagrangian-Eulerian and is a technique used in computational fluid dynamics to simulate fluid flow on moving meshes. The Peric codes you mentioned do indeed include ALE capabilities. The file you are looking for is called "ALE.f90" and can be found in the "ALE" folder within the "src" folder of the Peric codes.

In general, ALE codes use a combination of finite volume, finite difference, and finite element methods to solve the governing equations for fluid flow. The mesh velocity is typically calculated using the Arbitrary Lagrangian-Eulerian formulation, which allows the mesh to move with the fluid while maintaining a high quality mesh. The velocity of the fluid is then calculated using the Navier-Stokes equations.

If you are looking for additional ALE codes, I would recommend checking out the OpenFOAM software, which is an open-source computational fluid dynamics code that also includes ALE capabilities. You can find more information about OpenFOAM and download the code at https://www.openfoam.com/.

I hope this helps and good luck with your research!
