Interaction force

[Ludwigswe]

Hello!

I have compatible nodes in my model. When I open the Interaction forces in the global system table and select result for compatible nodes I get zeros in almost every compatible nodes. The only nodes i get some values (not zeros) in is support nods.

How is the iteraction force calculated?

Regards!

I get zeros in almost every compatible nodes. 

We know that 😞

You can get forces there for rigid links made by RLINKs.

Ok!

Is that a problem that you try to fix?

We can say that

I can not find anything about "Interaction force in globat system" in the Help,

do you have any information about it?

[Rafal.Gaweda]

No help
In short: forces "transferred" thru connection (interaction between nodes) presented in global coordinate system

[Ludwigswe]

So interactionforces is based on diplacement of the node times some springcoeffecient (stiffnes)?

Yes
