problem with KIVA3V
 

I am using KIVA3V to simulate a flow with an outflow boundary. The code
does not seem to be affected by ambient pressure at all (subsonic flow).
The exit pressure should equal the ambient pressure. The iterations do
not converge because exit pressure is turning out to be 1.0 (CGS units)
and I am not sure where it is being set in the source code.

Any help would be greatly appreciated. Thanks.
