Cyclic ACMI Boundary Condition for moving bar linear cascade
 
Dear Foamers,

I would like to ask a question regarding the ACMI boundary condition. I have looked at the oscillating inlet tutorial. Screen shots are of this case are on the link:

http://www.openfoam.org/version2.3.0/ami.php

I would like to modify this case, so that the excess of the left domain is mapped to the excess of the right domain, for a moving bar LPT cascade. Is there a simple way to modify the boundary conditions to allow this? Obviously the domain height needs to be equal for left and right. At the moment the information that leaves the left domain is lost and the excess on the right domain treats it as a wall.

Any thoughts on this would be greatly appreciated, I think I need to modify the cyclicACMIfvPatchField boundary condition, but the code is pretttty dense!

Thank you

Jack
