Meshing problem Gambit-fluent

Hello to all,
I want to do analysis of Flow through pipe using gambit-fluent software. Air as fluid. The fluid is coming form 5 mm diameter jet. It flow (V=184 m/s ) in 1.3m long pipe of 5.5 cm diameter pipe with a bend at the end.
1. I cannot considered a axi-symmetry problem. But yes symmetrical can be considered. This gives message large negative volume.
2. If i make fine mesh near jet and pipe, large no of volume is generated.
3. Controlling mesh by giving interval counts on edge, gives me unstable solution's.
4. controlling skewness, gives me large aspect ratio mesh.
Looking for your kind help.

avoid negative volume.
In gambit you can check where they are: examine mesh /volume....

Can you send a snap shot of your problem, with mesh for better understanding of problem.
