Autodyn flow out boundary error "NO UNUSED CELL ADJACENT TO FLOW BOUNDARY"

Hello,

I am trying to model the effect of detonation shock on a sand inclusion placed on my axis of symmetry in a 2d axisymmetric simulation in Autodyn. I am having trouble setting up flow out boundaries on the outside of the domain in the 2d axisymmetric simulations, it keeps giving me a fatal error saying NO UNUSED CELL ADJACENT TO FLOW BOUNDARY. Do you have any idea how to get around this?

Thanks,

Marty

Figured it out, needed to apply boundary to I and J lines on the outside of the domain rather than the outer blocks.
