Good afternoon everybody, doe
 

Good afternoon everybody,
does anyone know if there is integrated in OpenFOAM a DSMC solve and/or if there are any groups dealing with this topic.
Thanks a lot! F.

DSMC Solver
 

AFAIK OpenFOAM does not come with a DSMC solver.

For a successful attempt at using OpenFOAM for DSMC see the paper by Hauser and Allen of Utah State University. You can find it at:

Hi Sushant,

do you know if the code has been released by the Authors or is available somewhere?

Thanks,

in realease 1.6
 

dsmcFoam is distributed with release OpenFoam 1.6

Has anyone tried to couple dsmcFoam and OF (CFD-DSMC hybrid) ?

Hi all! I've been very busy with other stuff these days, only now i'm going back to dsmc... Unfortunately I have another problem.
Do you know how to set different initial particle numbers in different zones of the domain?
Do i have to prepare the mesh on purpose to be able to do this?

Thank you very much in advance

Marta

Sorry marta I don't know, would like to know myself.

But i think there is a way as at the beginning of every initialisation it searches for a POSITIONS file which should contain information about the particle cloud i guess.

No idea how to create this, but I think u can use former sim data to obtain such a file ?!

Ok, Archy, I will try and see ...i'll tell you how to do this, if i'm able to find out!

Thx

Marta

I think you can set the rhoN or rhoM to different values for different patches in the time 0 directory. I haven't tried yet, so I could be completely wrong. The only problem I see with this is that rhoM and rhoN are linked, so I would think you might need to change both. Just thought I'd throw it out there as an possible solution.
