Re: [Question #679748]: Error with lubrication law solver
Question #679748 on Yade changed:
Status: Open => Answered
William Chèvremont proposed the following answer:
There are multiple solver for this contact law, but in certain case, I
found that some can't give accurate results, just because of the
problem's stiffness. The iteratives solvers (dichotomy and Newton-
Rafson) are introduced for formulations without exact solutions.
Actually, the last solver (3, dimentionless exact solution with contact
prediction) will always give results, without any sub-stepping and/or
iterations, and should be used by default. Note that it doesn't
implement the theta-method and so, is full-implicit formulation.
