Default Neumann boundary condition

Hello CFX users,

I have to define the following boundary condition on a side of my volume : w=0 and (du)/(dz)=0 and (dv)/(dz)=0 (where u, v and w are the cartesian components of the velocity). How can I do this in CFX-Pre ?

Thanks in advance Paul

Hi,

A symmetry boundary should do the trick. Also a free slip wall may also be worth considering.
