(Linear) Contact Force, but No Contact Pressure

[NASAJPL]

Hey Y'all,,,

Linear Contacts... FEMAP / NX Nastran...

I got a Results to Data Table of

 225..Contact Pressure
 230..Total Contact Force

and when sorted for first 'Contact Pressure' and then 'Total Contact Force' I get this business, shown in the picture.

What's with the gap (blank) in the response of contact pressure for a certain grids, when there appears to exist some semblance of contact force on that thang.
Where's the disconnect?

Pre-thanks for entertaining this question. Have a neat day.

 

[FEA way]

What software are you using ?

Dear NASAJPL,
Without the FEMAP model in hand is difficult to know the reason of the strange results, try to post your model, or create a simply pilot study, this way we can investigate, thanks!.
Best regards,
Blas.
