Dear all,

I am using Nektar++(4.4.1) for computations of the flow past a square cylinder placed near a moving wall under the influence of buoyancy. I have used "HOutflow" boundary condition at the outlet as suggested by the user guide, but I got the wrong result.

Could someone please suggest a right BC at the outlet?

I have attached the mesh and condition files and the resultant streamlines.


with best regards,
Sartaj Tanweer
