source force and Periodic B.C. in Foam extend IBM
 

Hi,

I'm using Foam extend 4.1 IBM tools to mimic wall of the channel. and I use cyclic B.C. to connect inlet and outlet to simulate an infinite length of channel. I found there is something wrong in the cyclic B.C. Could anyone tell me how to correct it? and for another question, how to add source force to maintain a fix flux? The 'fvOptions' can't be detected by solvers in Foam extend.

Really appreciate your help!!!

:)
