Autodesk Simulation Mechanical and Multiphysics

All,

I have completed a mesh on an assembly, and found that some of the parts in the part tree have a small blue circular icon, with an "i". If I open the part in the tree, the icon also exists on the "CAD Mesh options" icon. Along with this icon, the original icon is highlighted red.

What does this mean? What can I do to resolve the issue (if there is on), i.e. refine mesh?

Thanks in advance for your thoughts!

To add, I am running Mechanical 2012, and this is for a static, linear analysis.

I had the same problem as you and I was distressed to see that there wasn't a solution ot your question.  After troubleshooting the problem, I found that the problem lies with Autodesk Fusion.  Somehow, that particular part got modeled as "nothing."  When I opened up my step file in Inventor instead of Fusion, I discovered that it didn't exist!  My suggestion is to delete that part from your model and redraw it in Inventor.  Don't use Fusion, I have been pulling my hair out ever since I started editing with Fusion and this issue just put the last nail in the coffin.

It pains me that no one could shed light on this issue since your first post.

Hi guys

The problem with that part is that it has feature matching issues. This is a typical CAD import problem in 2012. We fixed majority of such issues in 2013 when we changed our geometry kernel. 

If you can successfully mesh the part(s) there is nothing to worry about. If you have issues during meshing, you may want to go back to the CAD model and focus on small features and where multiple edges come together.
