Migrate CAD files to what CFD platform?
 

I have some 3D CAD files I made in AutoDesk Inventor that I want to model internal flow for. I am not sure what if any CFD solver or meshing software is able to convert IPT files into their native formats. I have some experience with Fluent and OpenFoam but I don't know if they can import IPT. Can anyone recommend a platform or a middleman for moving Inventor CAD files to something for Fluent or OpenFoam?
