Hello everyone.

I am using Ansys Fluent 14. I need to model a water surface which is constant in height. It's not a inlet, just top side of the model. Please check the attached figure.

At first I used pressure inlet , though it was not a inlet and got large reverse flow.

After that some one suggest me to use symmetry BC. I used that also. In that after some run, I got negative pressure , that means water surface was falling.


Any suggestion will be really highly appreciated.


Regards,
Tanjina
