Do you have any questions about the course "User subroutines in Abaqus"?

This course is made of videos (5 to 15 minutes long) which are organized into 12 chapters of contents as detailed above.

 

All the subroutines developed and lots of additional resources are given next to each of the videos, as well as more documentation and references to go deeper into all the details

If we need to develop models that require something more than standard features: boundary conditions, built-in material models, conventional finite element techniques... Then, the only way is to go for user subroutines, which provide all the flexibility that we need.

If you still have any question, you can always contact us directly at contact@tecnodigitalschool.com
