Elastic release in rotation joint (concrete)

Hello,

 

I have trouble modelling a Joint in a tunnel. The joint is made as an elastic realease with a k=25000 kNm/rad. However when i back calculate from the results Robot gives me in form of rotation and moment they don't fit together. For 2 of my joint the rotational stiffness increase and for one it decreases.

 

Do i need to use a different approach or can i force the program to run more calculation or something.

 

Best Regards Peter

Mind to compare values taken from the calculation nodes created by DSC algorithm for releases.

Hey Arthur,

 

I see my problem now, only thing left for you to solve is: How do I get node 101 102 and 103 to show up in my tables. I can see them in my view but can't get them to display in my tables.
