Hi,

I have a problem I can not solve.

I made a finite element model of a mechanical component using 3D squares linear elements.

After having played through static analysis with Optistruct : I need to export the shape of my static analysis results into CAD,Is it possible to export the mesh into a cad?

Best Regard,

Alessio

    Hi Alessio,

    If you mean you need to export the shape of your result into CAD,

    • You need to first export deformed shape from HyperVIew (file > export > deformed shape)
    • Import this file into HyperMesh,
    • Then create surfaces from the elements using Geometry > create > surfaces > from FE (If you have solid elements, you may need to use tool > faces to first capture the surfaces)
    • Then export the geometry to CAD using File > export > geometry ...

    Please see - HyperWorks Desktop Applications > HyperMesh > HyperMesh Tutorials > Geometry > HM-2050: Creating Surfaces from Elements
    for more details in doing this for complex geometric cases.

    Hi

     

    My analysis was optimization.

    I have export the 'solver Deck' from HYPERVIEW to HYPERMASH,

    At HYPERMASH i want to extract the new geometry from the imported (from the last iteration, at iso 0.3)

     

    How can i preform this?

    Since you already have the mesh in HyperMesh, you can use geometry page > surfaces > from FE

     

    however please note that after optimization, Geometry recovery in HyperWorks is done through a specialised tool called OSSmooth.

    OSSmooth is a semi-automated design interpretation software, facilitating the recovery of a modified geometry resulting from a structural optimization, for further use in the design process and FEA reanalysis.

    The interpreted design from OSSmooth can be exported as a finite element mesh in the bulk data format, as IGES surfaces, as a stereolithography file, or as a Hyper3D file.

    For more information on OSSmooth and how to use it see - http://www.altairhyperworks.com/hwhelp/Altair/hw11.0/help/hwsolvers/hwsolvers.htm?geometry_recovery_utility___ossmooth_2.htm
