Project Harmony for Simulation Moldflow is our free technology preview of a fully automatic Simulation Moldflow 3D mesher that can mesh a possibly invalid CAD model, i.e., has overlapping surfaces or small gaps between surfaces, and can automatically size the mesh elements based on local thickness and curvature. You can install this technology preview next to your commercial products so as not to affect your production workflow but be able to play with it. Project Harmony for Simulation Moldflow requires an existing Autodesk Simulation Moldflow license (2014 or later including flex).
I posted a new build the other day that extends the technology preview to December 10, 2015. Please try it and let us know what you think of this technology at email@example.com or the discussion forum associated with the project.
Automatic mesh correction prior to simulation is alive in the lab.
