I would like to ask some questions about how .bext files are used in LSDYNA. I have managed to successfully use the keyword *IGA_INCLUDE_BEZIER in R13, but in the R14 version this keyword was changed to *IGA_3D_BEZIER_XYZ, and it does not run successfully using this keyword. Please give me some use cases on changing the keyword. In R15 version I found that this keyword changed again to *IGA_3D_BASIS_TRANSFORM_XYZ, I don't know if there is any difference in it. Please give me some help in using it.

Hello yitao,

Ansys employees are not allowed to upload files on the Ansys Forum and so I cannot send you exemples. Please consult the LS-DYNA User Manual Vol I for more information on keywords:

LSDYNA Manuals (ansys.com)

We have an introduction to IGA class available:

https://www.dynamore.it/en/training/seminars/iga/iga

You can register and learn more about the keywords.

Let me know how it goes.

 

Reno.

Dear Reno Genest,

Thank you very much for your reply. I have downloaded and reviewed the user manual, but it doesn’t provide detailed information on the use of .bext files. I have also looked into the IGA introductory course, which covers the basics of IGA, but I am still unclear about how to use .bext files in the new version.

If possible, could you please send me some examples of how to use .bext files? My email is elii.yang@outlook.com. I look forward to your response.

Best regards,  
Yitao
