Hi all,

I have a simulation set up where the geometry is split across 2 mesh boxes (to representation two different directional flow that meet). The issue I am having is that the flow and respective data is not flowing through one meshplane and into the other.

The mesh planes (both on symmetry default) are butted together on the same co-ordinate, so data should be moving through freely but it is still resulting in a liquid bounce back effect in each respective mesh blocks. Can I ask what can be done to rectify this?

Much appreciated

it would be useful if u can provide any image(s) for further understanding

Have you tried setting one boundary to outflow and the second to symmetry?

You should offer some pictures about your model and meshing
