Unexpected results in joints rotation

RE: Unexpected results in joints rotation
Hi Bas,

There are several problems with your model.
First the following Warning has been given: 'Iteration criterion not satisfied' meaning that there is no equilibrium yet. If you enlarge the number of iterations to be performed, you will see that equilibrium is reached after 93 iterations.
But the main cause of instability is the specification of free axial displacements in the joints of 500 mm, both for tension and compression. This is also physically impossible for 2 joints in a pipe section of about 1 m long!
If you change the 500 mm to 50 mm (more a real value), then you will receive reasonable results in 26 iterations.
