There's a problem with mesh - try Meshing forum.
As it seems to me, you have some faces overlapping - you didn't done face connection? Or would you use non-conformal mesh? in gambit, face connect command could help after geometry construction.

thank for you reply, i use ICEM for meshing, i still beginner in this software, how to solve it, can you teach me, this is my e-mail, m.zarithothman@gmail.com, please
