Problem with mesh generation
 

Hello everyone. I am performing a cfd simulation of a centrifugal pump. I used bladegen to model the blade and volute and converted them to iges files. I modeled the other parts and made an assembly in Autodesk inventor. I converted the inventor assembly into stp and iges formats. I am not able to create the mesh for the impeller. The mesh is generated for all the other parts of the assembly. The impeller is being recognized as a surface body. Help me with this. Thank you.
