I am trying to observe the ties that break in a tiebreak contact. For this, I am taking the results of binary intfor. With this segment, results can be observed. But when I switch to nodal results, eg. I want to see nodal contact gap or nodal interface force, but it all turns grey. I.e. no results are being shown. I tried sharing this file with LS-DYNA support. They say that it was possible for them o view these results. But for me its still all grey. 

Can someone help me with these?

Hi @mangalath

It could be the version of LS-PrePost that you are using. Could you check with LS-DYNA support and ask which version they are using?

@negativevolume  Support checked with me which version I am using, they said they used the same one and still it was possible for them to see the results.

Okay so it sounds like it's just an issue with getting it to display correctly on your end. Probably just a parameter that you need to toggle. Can you provide a screenshot of what you are seeing and what are expecting to see?

when I try to view the nodal results of the interface as you can see in image, it is just grey. No solutions and nothing can be obtained here. I will share the contact details and database options i set below.

 

Is there anything more that you will require? This contact is described between two blocks, with the block on top given an initial velocity generating a stress wave in it.
