Yes, you can use VABS Abaqus GUI: https://cdmhub.org/resources/939 if you have Abaqus. We are also currently developing a code called PreVABS to help generating inputs for VABS. If you need it, please let us know.

So I have downloaded the package.
Is it normal that when i unzip the name of the folder is "abaqus-swiftcomp_gui" ?
You should modify the explanation on the pdf because know we have to write the correct name of the folder in "abaqus.aev".
I did it by my own way but maybe some peoples will not understand.
It's ok to create layup but know I have an other error when I'm trying to Assign Layups.
Recently we published a new preprocessor for VABS, PreVABS, on cdmHub. You can download it here: https://cdmhub.org/resources/1597. This tool allows you to build your tube model through a few parameters automatically, instead of clicking in a GUI. I have prepared the package of input files for your model. To run it, first download and unzip the PreVABS package. Then download and unzip the attachment into the root directory of PreVABS, for example c:\prevabs-v0.3\. Open cmd.exe and change the directory to this location, and run the following command:
prevabs -i tube/tube.xml
The VABS input file will be generated in the tube folder, 'tube_vabs.dat'. If you want to see the meshed cross section, you can add another option '-v' in the command and run. If you want to change the outer radius, you can go to the file 'baselines.xml', and change the number between the tag '<radius>'. To learn more details, please refer to the manual.
If you still want to use Abaqus, two things might be helpful. First, it seems that the thickness of the tube in the Abaqus sketch does not match the total thickness of the layup used. Second, by 'partition' I mean to partition the part using x-y plane or x-z plane, so that the cross section is divided into upper-lower halves or left-right halves, and then assign the layup separately.

To generate VABS input File, is there a way to write input file.
I want to generate it for a large structure with lots of nodes.

For Abaqus :
I have already downloaded it but, I had a problem when i was creating the Layup.
Indeed i Have a message box "global name 'mid-name' is not defined'"
I don't know how to solve it. I join XML files in attachment.
I will be interested about PreVABS please.
thank you Doctor Yu

Please see in attachment.
Thank you for your help

Thank you for your advice. I have just changed the folder name back to the previous one.
For your model, can you try to partition the cross section into two parts and assign the layup again?
Salim Chaibi @ on
Why should have I to partition ?
Su Tian @ on
This is the limitation of the current version. The 'assign layup' function needs to find two ends of the laminate.
Salim Chaibi @ on
okay, I did it but it still doesn't running.
I join my Abaqus cae file.
If you can take a look please.
Thank you
