high speed compressible flow using Multilevel LBM

Dear Friends
I have recently started workong on LBM. I am working on multilevel LBM for the high Mach number [url=http://prola.aps.org/pdf/PRE/v68/i1/e016303]. I am stuck with the boundary conditions.
can some one guide me?

I’m also interested in LBM for high Mach flows.
Maybe you or anybody who works on the same problem can post some experiences with the implementation of this paper.
Did you get any further with your problem?


I’m working on the same subject and I’ve got the same problem I think. As far as there are more unknown discrete directions in the boundaries than the equations, I can’t implement inlet or outflow boundary conditions.

In case you’ve got the answer! :wink:
