Dear All,

As part of my work i have been looking at applying a buffer zone into the rhoPimpleFoam solver to damp variables at the boundaries to prevent reflections, particularly relevant to acoustic problems.

Ive read some posts in the past on this topic and i was wondering if people would be interested in getting the source code for the modifications i have made? Im just putting the final touches to the code/commenting/tidying up.

I have also created compressible versions of the DDES and IDDES turbulence models from their respective incompressible versions.

All the best,

Your code should be very interresting for me, I need a sponge layer to damp vortex and I didnīt find this feature in OpenFOAM... So If your are aware to share your code, I am interresting.

Hi Micheal,

I am currently simulating a subsonic jet (Mach = 0.51) and I could benefit a lot from your buffer zone code.

Beyond that I have also been looking for compressible DES models. Do you think you can share them too? Also, have you been able to validate them?

If you need more details on me then please let me know. I think I would be able to explain why am I not coding these things on my own - well it all comes down to time as you know.

Thank you very much.

p, li { white-space: pre-wrap; } Hi Michael,

What a nice offer!

I am working on aeroacoustics. Currently I use the convectiveOutlet bc, which works pretty well. I was also making some attemps to implement a buffer zone, but it actually makes things worse in my case (probably because I am new to OF programming). Nevertheless, I would be very interested in your code!

Let me know if you need any information from my side.

Thanks in advance!
