i have a important problem!!!!

i modeled cloud point to solid geometry.geometry is consist of assembly of blade and housing. And geometry is piecemeal
I imported assembly geometry to design modeler (attached fig).and enclosured blade. enclosure box is housing. I want to transfer model from design modeler to CFX mesh.after a long time meshing tab is empty(attached figure) and there is no geometry in meshing tab.
How can solve this problem???

maximum tolerance between my model and real model is 0.039[mm].my project isnt an industrial work.it is a student project.in that case 0.039 tolerance is not important.
