How to set Contact Initialization in Abaqus/Explicit? 1

[dfgsdfgfd]

Hi everyone,

I'm running an ABAQUS/EXPLICIT simulation where I get a lot of initial edge-edge overclosures.

In both, the GUI and with Python, I can set the settings for these overclosures within the "Contact Initialization" tree (e.g. CInit-1). However, when I create the "General Contact" in the "Interaction" menu, I cannot select CInit-1 as a property. In the ABAQUS/STANDARD simulation, I can select it. Please see the attached image.

Is it not possible to set Contact Initialization in EXPLICIT or am I doing something wrong?

Thanks very much!

This option is not available in A/Explicit since it is not necessary. A initial penetration is generally not allowed in Xpl, so an adjust is always done. And a gap is no problem, since Xpl cannot have a numerical singularity because of missing contact definitions or a gap in contact.

Thank you very much for the explanation, Mustaine3. I really appreciate your constant help in this forum -- not just on my questions, but on other questions that help me and everyone else, too.

If you introduce inertia using Abaqus/Standard, then you will not run in to numerical singularities either. However, inertia will result in transients.
