Hi Abdulhaq ,
thanks for your reply , But I want to know how can I creat this patch? I think adding this patch manually in the boundary file is wrong because I dont know anythings about startFace.... correct me if I am wrong... Thanks, Sasan. |

If you notice the start face for the inlet is the same as the empty patch (wall), so just take the starting face for any patch.

Why do you want to create an empty patch anyway?

You need empty patches for the attachDetach modifier, so that's one usage. Just remember to update the number of patches at the top of your boundary file, otherwise your solver will crash.
Also, it seems safest to add empty patches at the start of your boundary file, in my experience. |
