Hi,

I'm a Master student doing a project on water visualization. I'm currently looking into analyzing the structure of water that flows around buildings. Of course, I need a parametrize-able simulation first.

Doing a full 3D simulation seems like overkill to me, since I am only interested in the surface. So I'd like a 2.5D simulation. I was thinking about something like a Shallow Water solver, but there are probably other solutions as well..

To me, SU2 looks like solid (pun intended) software for this type of usage. However, being new to CFD, I'm having a hard time figuring out how to achieve a simulation like this. I couldn't find any documentation about or sample cases doing this kind of thing. From what I have seen, test cases generally output pressure and other data, but no surfaces of any form.

Is SU2 suitable for this? If so, where do I start with this? Any help or resources would be much appreciated.

A possibly relevant side note: I prefer to work in Windows, as I have really limited experience with other systems.

Thanks in advance,
Selmar

Dear Selmar,

SU2 is a very flexible platform and it should be easy to implement the shallow water equations using the already implemented incompressible 2D Euler solver.

If you are interested, please folk the main code and keep us posted about your progress, this is the kind of implementation that could be in a SU2 release.

In the SU2_IDE you will find the Visual Studio files if you want to use Windows.
Cheers,
Francisco

Okay, I'll give it a try! It's really nice for a change to find actual project files!

There are a few issues however; the solution file adds the SU2_MSH project twice. In addition, it attempts to add a project called SU2_SMC, which doesn't exist. I assume I can ignore this, just letting you know.

I've been looking through the code and read the documentation I could find, but I've come to the disappointing conclusion that I don't understand enough. I need some help understanding the solver structure.

I believe I figured out how to write the shallow water equations in a way that abides to the PDE structure SU2 requires. However, I don't know where or how to modify the standard euler solver so it can solve these equations. I don't even understand where (and to a large extent how) the current equations are defined. What pieces of code should I be looking at?

Aside from this, I have trouble understanding the function of all the methods and variables in the class. There's probably a lot I don't need?


I feel it is quite demanding, but I would like to have explained in a bit more detail how I go about implementing the shallow water equations.

Hi,

Nobody with a few tips? It'd really help me out!

Thanks,
