Plot mesh from hypermesh/hyperview to CAD (solidwoks)

Rahul_P1

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.

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
