Contact doesnt work

Altair Forum User

Hello everbody,

 

i have a problem with a contact condition between two components. Everytime when i view the results of the analysis, the master surface 'ignores' the slave surface. The solver doesnt find any contacts between this two parts. Im using optistruct with non-linear quasi-static analysis and i defined a PCONT property for my contact condition (i need a slide condition). I tested many different search distance and clearance settings, but neither of them works. i really wonder about this, because i defined three other contact conditions (with the same settings) within this assembly which working without any Problems.

I tested my single contact condition with a force load and a moment load. i found out that theres only the problem when im using the moment load, with a force load the components recognizes a contact. In my assembly are three forces which causes a moment load on my problematical contact condition. Can someone give me a helpful hint ?

 

Thanks!

Hi Chris_hyp,

 

Have you tried with SLIDE condition in CONTACT card instead of using PCONT?

 

Also, please read about the search distance and how it is calculated for different contact types.

Hello,

 

i tried to use the SLIDE condition instead of the PCONT Card and i worked with a 'better' search radius. So what can i say, it really works! Thank you very much for the help /emoticons/default_wink.png' alt=';)' srcset='/emoticons/wink@2x.png 2x' width='20' height='20'>
