How can I clean up the assembly in Solidworks before exporting to Ansys?

I made wind turbine blades and hub and assembled the parts. I imported the wind turbine into Ansys fluent for simulation. In Designmodeller, under Details View, I changed Simplify Geometry and Simplify Topology to Yes . I generated my model and used Boolean to unite my 4 parts into a single solid. I used your Tools-repair for further repairs, but Repair Sharp Angles, Repair Slivers and Repair faces are failing.
So I want help on how I can clean the geometric model in SolidWorks before exporting to Fluent.
