Non Linear CBUSH Element

Hello,

 

for my master thesis I have to work with non-linear CBUSH Elements. I have created a TABLED1 with the forces/deflection. In the PBUSH Property I selected the KN_Line assigned the TABLED1 to the dofs. For the non-linear simulation, I have created a NLPARM card with default settings. At the end, I have created a non-linear quasi-static Loadstep.  But when I try to run the simulation, I get the followin error message:

   'PBUSH          2'

  *** ERROR # 1000 *** in the input data:
  Incorrect data in field # 3.

 

Could you tell me, where my mistake is?

 

With regards,

Metin
