periodic boundary condition for one face of a (3D) rectangular duct domain
Hi all,
I am new to CFD and i m simulation on the film cooling on a flat plate, and i used gambit for modelling a 3D rectangular geometry as a domain. The bottom face of the rectangular duct is the taken as the test plate. I gave the following boundary conditions:- 1. duct inlet > Velocity inlet 2. duct outlet> pressure outlet 3. test plate > wall 4. Top side> wall( opp face of test plate) 5. right side face> symmetry 6. left side face> Periodic After that i did export > mesh, but the file is not exporting successfully. It is showing some errors with the periodic boundary condition, they are warn: boundary entity periodic side shadow does not contain any valid entity and is not written. error: periodic boundary entities are not specified on the same boundary entity. please help... what is the error and how can I resolve it... thanks in advance |
