Quality checking - intersections

Hello All,

I have a small question regarding Hypercrash. I am checking the intersections and penetrations in my model using the Quality menu – check tree selection and I get intersections between each part. Intersections between two parts are highlighted. What does number below “Int.” correspond to? Is it the number of intersections between the two parts or the number of elements intersecting? I also checked the model using “check all solver contact interfaces” under quality menu and I get a different result. Even though there are many elements intersecting between two parts in two different regions, it is being listed as only one intersection. I don’t seem to understand the difference between these two ways of checking the model intersections. Could you please provide me some light on understanding the difference between these two ways of checking the intersections in the model?

    Sorry for the late reply.INT is for no of elements & it works fine for me when i check using 'check all solver contact interface'

    See attached screenshot.

    Thanks Rahul.

     

    I found this in the hypercrash manual: 'Int' is actually the number of intersections in each part pair and not the number of elements.

     

    Thanks for the information.

    Please see the snapshot below from hypercrash:

     

    Even though there are two intersections being displayed, why does it calculate as only 'one' ?

     (1 displayed under the 'int')

    Sorry for Typo on my INT comment.Could you try intersection check on latest version 14.0 or any other lower version?it worked fine for me on Radioss user profile.

    Thanks Rahul. I'll try with hypercrash 14 if it is available and get back with you.

     

    I have one other small question, what does the 'Couples of parts' represent (shown in the same line as intersections)?
