    import hypermesh in workbench

    Kunggu, Sorry I've not seen that error when loading HyperMesh CDB files into Ansys. Would someone on the Ansys page know the answer? Regards, Ben

    Hypermesh connecting meshes

    The Edges panel on the Tools page is the easiest way to check for disconnected elements and merge coincident/detached nodes: 1) In the edges panel, select the components or elements you suspect have detached elements 2) Click find edges to draw red line (plotel) elements at the edges of the...

    Topography Optimization with OptiStruct - Error

    Jo, I did some more research and this error is often caused when the base thickness is the same as the shell thickness in the PSHELL card. Both may be equal to 1.0. Optistruct defines the design space as the difference between these thickness values. When the difference is 0.0 there is no...

    Topography Optimization with OptiStruct - Error

    Jo, Did you apply a design constraint? Otherwise the optimized solution is to remove all material and let the node deform into infinity. The simplest design constraints to define are displacements or compliance under the Responses panel. Then you can set the limits of the response under the...

    Can anybody check this simple model for errors?

    Yes, the error is there are two tria3 elements with id "11". Looking at the id ordering in the file, I'm guessing the duplicate should have an id of "21" instead of "11".

    Topology optimization: entire design volume disappears

    Yes, you can use that link for contacting support. You can also send an e-mail to hwsupport@altair.com which I like because it saves you from filling out the web form.

    Topology optimization: entire design volume disappears

    HugoR, I pinged the Altair support team and the Director of Support and if you could contact support with a model they can help you. We can then post the final solution back on eng-tips for everyone to see. The error message you seen when going through the tutorial is mostly likely caused by...

    Merging nodes between components

    HugoR, Did you import surface data or mesh? If you imported a mesh you can use the equivalence button in Edges panel on the Tools page to combine nodes together. If you are working with surfaces, on the Geom page there is an Edge Edit panel. You access Toggle then click on the surfaces' edges...
