HELLO, 

I want to fix the joint between two line bodies It is just a beam column joint. But the line body is (BEAM189). I tried fix rotation but it fixed the whole rotational DOF which I dont think is a correct way of defining a fix joint.

Insert a Joint under the Connections folder.  With a Joint, you get to pick an entity on each body to hold that body and it automatically creates a Coordinate Systems to use to define the Joint.  There are six degrees of freedom between two bodies.  If you select a General Joint, you can pick and choose which DOF you want to fix and which ones you want to be free.  Some combinations have been given meaningful names like Translation or Revolute.  You can fix all angles and let the two bodies have translational freedom in 3 axes.  That would be an odd combination. What combination do you want?

Thank you, Peter for the quick reply, my computer crashed so I couldn't catch up with you. Sorry for my late reply. 

I will consider the fix rotations but let all the translations free. I don't know would that be an odd combination? I tried to do it using beam-column as different parts and it was possible, but when I merged all the parts in the geometry, I couldn't assign the joint. What kind of joint is defined by Ansys in default?

The default joint is Fixed, but you should use the joint you need to model the structure as designed.
