Hello. I need to connect bar-a and bar-b so that each is free to rotate around global x or z, respectively - bars are modelled as wires. I thought to use a revolute connector between each bar and a coincident RP, then to connect the two RPs via a universal joint connector. However, abaqus returns the error: "The angle between the axes specifying the shaft directions in an universal connector is larger that 90 degrees. Please check model".
I do not understand what I did wrong. My details are:
RP-a: connects to bar-a through a CONN32 revolute +align joint with Csys axis 1: 1,0,0, axis 2: 0,1,0. // rotates around first axis,x
RP-b: connects to bar-b through a CONN32 revolute +align joint with Csys axis 1: 0,0,1, axis 2: 0,1,0. // rotates around first axis, z
RP-a: connects to RP-b through a CONN32 universal +align joint with Csys axis 1: 0,0,1, axis 2: 0,1,0. // blocks second axis, y)
Any idea? Thanks a lot!
