nThose are great tips doing them separately. But forgive my stubbornness because I feel like I am close to producing what I wanted. nI just realized that i did not click on the share button in workbench and once i did, Ansys was able to set the boundary condition according to what I named them as. But I am now facing one new issue that is the interior showing up as a wall boundary condition while also showing up as interior boundary condition. That's the remaining issue before I could successfully run the simulation.nWhat might be the cause of this problem sir? Also I am not using student version so I will clean up the mesh to a finer setting once I can run the simulation. nI know I am pushing here but the zip file is attached below if needed. THANK YOU!!!nn
