Mistake when importing an input file (*.inp) from Abaqus

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 afura,

Thank you very much for your quick response. Sorry but this is the first time that I export from Abaqus to HyperMesh but, how I can export the abaqus model in flattened format? Thank you very much.

Dear friends,

Here I found the solution to my problem:

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"?>

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