My question is about suggesting a new time increment in a step in abaqus. My friction coef is varying with time. I am using fric_coef subroutine to impose this variation.
I would like to reduce the time increment when near an abrupt friction change. Now, I am considering small time increments during all the step although I need them only at very short periods of a step (earthquakes).
Looks like It is not possible to do it within fric_coef subroutine and that only in FRIC subroutine that PNEWDT appears. Is there any other way to solve this problem because I dont know how to
use FRIC just to change the friction coef ?
Thank you for any help.
