Dear friends,

 

I have a model calculated in Abaqus, and I want to analyze differences between this software and Optistruct. When I import the *.inp file into Hypermesh, the model is not imported properly. Why is happening this? I attach two pictures.

 

Thank you very much for your attention.

 

Regards,

JJJ

    Most likely your abaqus mode has *part, *instance structure. You need to export your abaqus in flattened format.

    Dear friends,

     

    Here I found the solution to my problem:

     

    https://abaqus-docs.mit.edu/2017/English/SIMACAECAERefMap/simacae-c-dbsflatteninput.htm

     

    In Hyperview, is it possible to visualize results from a *odb obtained in Abaqus?

     

    Regards.

    Hello Livil Lyle,

     

    Good morning, sorry for the delay to answer but I have been very busy this time. Could you please tell me how I can view the odb results in Hyperview? Thank you.

    Hi JJJ,

     

    Launch Hyperview -> Input the model and result file path

    <?xml version="1.0" encoding="UTF-8"?>image.thumb.png.63bbfae652f25c249bde68705969ce75.png

     

    Click on Contour -> Select Result type, Result Component etc and press Apply to visualize the contour.
