Complicated Part Not Importing Properly and Can't Tetra-mesh

Hi there,

 

Created a fairly complicated part in Autodesk Inventor over the past couple of weeks.  It looks this way as a result of a topology optimization run in Optistruct a while back.
(attached is an image of the part, as taken in Inventor)

 

However, now that I have drawn the part in Inventor, I am trying to bring it back into Hyperworks to analyze the part.  However I cannot use the volume tetrameshing on this part.  The imported IGS file seems to have gaps where there shouldn't be, and there are red lines appearing on the model when I try to do the tetrameshing.

 

I should mention that I did do a lot of filleting of sharp edges prior to bringing the part into Hypermesh.

 

Any thoughts or suggestions?

    Hi,

    did you try following help topic HM-3270?

    you can find it in menu help>HW Help home  >>> Hypermesh Tutorials

    and learn how to clean up geometry before meshing

    Hi tinh,

     

    Thanks for your response!

     

    I exported the file as a STEP file instead, and it turned out to work just fine, no cleanup needed.

     

    I read something online saying that the IGES format hasn't been maintained for the last 20 years, so I think that it was the problem.

     

    Thanks again!!

    IGES is only my latest working option. It's better with STEP, Parasolid.
