(OP)

Hi all forum,
i'm novice in abaqus, i'm modeling 3 flexure test of a sandwich i have always this error can one help me
Error in job Job-F: Resolution of initial overclosure may have caused excessive distortion.

RE: overclosure caused excessive distortion

Initial overclosure refers to contact surfaces interfering each other. If this is in the start of an analysis my guess is that you have a singular problem i.e. something is loose so that you receive "heavy displacements" when applying your load meaning that Abaqus cannot resolve the contacts properly. Excessive distortion of elements can very well be a secondary effect to this.

RE: overclosure caused excessive distortion

You could also have too much interference to begin with. If the interference is genuine, use interference in the contact definition. Otherwise correct your model. Or try Automatic overclosure tolearance in contact controls.
