I am trying to model an actuator that looks something like this (excluding the caps) which is inspired by this fibre-reinforced actuator. I have also written a python script to do the same but I am getting the following error :
which leads me to believe that there is something wrong with my tie constraints.
These are the steps that describe my work:
1. Inner First Circle
2. Inner Second Circle
3. Extrude
4. Outer First Circle
5. Outer second Circle
6. Extrude
7. adding tube I as an instance
8. adding tube II as an instance
9. merging instances to make merged actuator
10. create point for fiber I
11. running fibers script (to make helix)
12. create point for fiber II
13. running fibers script (to make helix II)
14. Add fibers I and II to assembly
15. adding fiber I and II instance
16. DEFINE elastosil material
17. DEFINE kevlar material
18. creating elastosil sections (for tube I)
19. creating elastosil section II (for tube II)
20. creating kevlar/fiber section (for fiber I)
21. creating kevlar/fiber section II (for fiber II)
22. assigning sections for merged actuator
23. assigning sections for fibers
24. beam section orientation for fiber I and II
25. create inner surface for tube I
26. create outer surface for tube II
27. create step
28. Boundary conditions (??????)
29. Amplitude
30. Apply load
31. mesh control
32. mesh element type
33.. set seed
34.. mesh generation
35. mesh fibers
36.. mesh settings for fibers
37. mesh
38. tie constraint for fiber I and tube I (outer surface)
39. tie constraint for tube II (outer surface) and fiber II
Any recommendations are appreciated
