problem in simulating a walking man with its exhalation
 

I want to simulate a walking man with its exhalation, but I have a problem ito simulate the exhalation to move as dynamic mesh with the man, please any help

What kind of help are you expecting??? Do you think that we can see your screen, see the error, and see what you should change?

thank you for you reply and concern,
i want to simulate a walking man with its exhalation using profiles ( dynamic mesh). the man walked but the exhalation from it wasn't simulated as i define it as ( velocity inlet) [it was simulated in steady state but wasnot when using unsteady and dynamic mesh)
i have attached the dynamic mesh setting and B.C
