Hi everyone,

Im M.Sc. student of mechanical eng. I was modeled crack in a cylinder with X-FEM method in Abaqus software, but I have some problems:

1- when I want to see crack propagation in results, although some of elements are failed (according to STATUSXFEM contour), but I can not see crack propagation in model. What items must be activated for this purpose?

2- In step module, when I set minimum time incrementation to 1e-20, I got this error: machine precision require a time step greater than 2.2200e-16.

I know that default value for minimum time incrementation is 1e-15, but I want minimum value than that and I do not know how to set that?
