Thank you very much for your ABAQUS-VABS GUI , It's a great help for VABS pre-processor。
But I had a problem recently, I create a following sandwich structure for example:
I follow with your PDF file(General_Cross_Section_Analysis_-_Step-by-Step.pdf),
So, I imported the material file into Abaqus, then I used “New layers” button and “Fast generation” Method to create 1 layer of glass fiber on upper surface like this:
Then I used “Assign Layups” button to assign layup, but it failed with “Feature creation failed”.
Does ABAQUS-VABS GUI cannot create a single layer or my process is wrong?
