Hi,

I have problem with using field variable in Abaqus. I was Abaqus/CAE to model my problem, but when I add field variable option in Input file, I got this error:

Hi Everyone,

""""

I was apply Field Variables to change material properties in simulation, but I got this error:

in keyword *FIELD, file "Job-2-Copy.inp", line 5575: Unknown assembly node set _Pickedset2

in keyword *FIELD, file "Job-2-Copy.inp", line 5612: Unknown assembly node set _Pickedset2

Hi everyone,

I'm 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?

Hi Everyone,

I must doing a project for fracture mechanics course. I'm so confused for this. Can anybody  help me?

Thanks.

Hi Everyone,

 I'm a M.Sc. student of mechanical engineering. my thesis is fatigue crack closure simulation with interface element. I don't know how start with interface (cohesive) element. I need some fundamental text on interface element.

If anybody knows about these topics, I would appreciate for helping me.

Most thanks.
