I've done a simple revolve assembly, meshed with tetras and contacts with finite friction; cyclic symmetry constraint.
As in the helical assembly, the analysis doesn't converge at the beginning.
I noted that in reality the analysis doesn't converge only at the 2° pass of the Single Pass Analysis.
The 1° pass, where all the p-elements have a polynomial of third degree, has always been completed.
I've tried analysis with:
- Automatic steps within range
- User-defined output steps
- 20 and 40 steps
- Auto definition of steps
- user definition of time step with the first 10 pass very small
but the result is always the same: the quick check analysis goes and in the single pass goes only the 1° pass.
