ABAQUS CTF 1

[a126z]

Why is it not possible to output the connection force of a rigid connection of multiple separated lines using ABAQUS CTF? I wonder what the problem is besides? Even though the output CTF is set in the field output, I can't find the CTF in the ODB file, or all the CTFs and CTMs are 0. What is the reason for this?

 

[FEA way]

Which type of connector are you using ? Also, check the warning messages.

I would like to inquire what is the difference between the two connections below? (1) With a connecting beam in the center, the end points of the connecting beam are connected with beam connectors; (2) Without a connecting beam in the center, the two points on the beam are directly connected with beam connectors.

 

[FEA way]

What kind of connection behavior do you want to model here ? BEAM connector provides a rigid beam connection while beam elements are normally deformable.

Thank you for your help. I understand the difference
