solving contact constrain

[scirer]

I wanted to know what the percentage of progress represents when the solver calculates the non-linearity of contact between components in which the friction has been inserted.
I have a simulation that stops at 25% advancement. - 25% of what? That's what I don't understand! !

represents the state of progress in the resolution of the equations that must solve the contact (movement).
I was also born that when it comes to 25% it blocks (I don't know what it does) and it takes some time to go ahead....but be quiet that comes out and then pass to the calculation (rapid) of tensions.

when performing a nonlinear calculation, the problem is automatically divided into a series of linear substeps. often the first substep is the most critical, so if you block everything at the first substep try to repeat the calculation with minor loads or simulating only some contacts and check that the problem is well placed from the static point of view, if it is then try to inject mesh.

other times the model, or better the solution, does not converge and continues to work without stopping!! !
