Warning about concern nodes in contact type2?
Best Answer
-
Depending on your settings for ignore and spotflag, this will be related to secondary nodes that do not have a good projection normal to the main side... e.g. below, the nodes of the plate are tied to the segments behind. But the nodes on the end of the plate overhang the edge (so there is no normal projection)
This results in message to check those 7 nodes:
If you are concerned about the warnings, you can remove those nodes from your interface, or if you set 'IGNORE' flag = 1, then the nodes will be automatically removed, and you will get a message about that instead of the warning above

When I'm using IGNORE FLAG = 2.
Number of slave nodes in tie contact = 288 nodes.
And I get warning that:
- 77 concerning nodes
2. 211 nodes will be deleted from tie interface
It means that even 77 nodes have poor projection, but they still can create tie contact right?
Because when I'm ignore the warning and run simulation, parts are still be tie together.

Yeah, basically 77 have 'poor' projection but are 'close enough' to still be tied, so it recommends you check them, the 211 are far enough outside that it rejects them completely, but you say you only have 288 total? So all your secondary nodes have bad projection to some degree? if it is tied, then ok, but the geometry must be a bit odd here?

Yeah, really thank you.
The geometry I'm working on is a little bit odd.
