Question about Abaqus-VABS GUI

  1. zhao mengmeng


    I have read the tutorial about the usage of Abaqus-VABS-GUI-Code,  and I am working on my own case. I use NACA0012 as the airfoil along with single web, but after run the script in Abaqus 6.14, it always fails with an error of " The cut operation failed because the base instance was not modified ". This situation happens when I change Web's position along the chord direction. I am wondering what was wrong. Could you please give me some advice?

    Thank you very much!

    Hi Mengmeng,

    Thank you for your interest in the GUI!

    The problem is that the length scale is too small. I find that the chord length is just 0.0762 and the thickness of a layer is only 0.000127, which will cause some precision problem of numbers in Abauqs. When I increase all length by 1000 times, the script runs without error. So I suggest you to change the length unit to a smaller one. I think you need to change the following:

    • Airfoil.xml: chord_length, mesh_size;
    • Layups.xml: thickness;
    • Materials.xml: density, e, g.

    Please let me know if you have other questions.

    Best regards.
