Do you know how to convert a STL mesh file into solid part for finite element analysis?
Using stereo-photogrametry tech I have a geometry of the structure in the STL format. Now I try to import it into hypermesh for FEM analysis.
I will appreciate it if you help me.

    STL files can be imported into HyperMesh, You need to use File > Import > File type > STL and then choose the file. 

    Once the STL file has been imported you can then use Geom > surfaces from FE and select the highest complexity in this panel > select the elements to create surfaces from STL, hence you can create geometry from stl.

     

    To directly solid mesh your STL use ShrinkWrap
    You can achieve a good tetramesh for all purposes, using the Shrink Wrap panel. The shrink wrap can generally be used as a quick mechanism to generate solid meshes.

    1. Go to 2D > Shrink Wrap panel.
    2. Here there is an option generate solid mesh – this will produce an all-hexa or all-tetra mesh based on the selected elements or geometry.
    3. Make sure the generate solid mesh checkbox is active
    4. This will expose a tet collapse input, please try several input values depending on your quality requirements.

    Hi Rahul,

     

    I can't find the following path:

    ' File > Import > File type > STL '

     

    I can only see the attached options.

     

    My problem: I have a stl mesh file of a simulation programm and want to convert it to a solid and smooth the surface for an analysis in ANSYS.

    Can you please help me?

     

    Kind regards

    Alex

    This import option under FEM is available in full version not in Student edition.

    Hi Rahul Ponginan,

     i done all what you said, but creating some surfaces was failed .does it refer to my Complicated geom?

    can you help me what should i do?
