How to get over single edge and multi edges in my case
 

Hello, i'm a new guy in icem cfd.... and when i input the geometry i made using solidwork, it seems the algorithm was not fit and the system keeps warning the single edge and multi edges problems,,, it is a rather complex model with thin walls and i tried to build volume mesh.... Do you guys get some answers? If you need files, i think i can leave them in your mails... thanks!:):)Do you guys have some standard solve for multi or single edge?
