flow around a plate- Negative absolute pressure???
 
Hello,

I want to model a flow around a plate (Length 100mm and width 3mm) in a domain (Length 1000mm, and width400 mm). As a boundary conditions, I put a velocity inlet and mass outflow. and I kept the operating pressure as atmospheric pressure.

For low velocities (1m/s, 3 m/s), the results seem to be good but for higher inlet velocities (8m/s) I got NEGATIVE absolute pressure??? can someone help me with this????

Thanking you in advance .

Tania.
