Ok this is probably an easy one to answer for most but I just can't get this to work or even understand why its not working.
I'm just trying to analyse a simple link in between two ball joints.
The link is held by one spherical ball and the other end moved towards it (compressive) to create a spherical load. I would expect this part to bend in a single curve (rather than an S bend).
I have been trying to analyse the link without the spherical joints modelled to avoid using contacts for simplicity. I thought the best approach would be to create a single point at the centre of the ball joint and 'spider' that to the ball joint and apply the constraint to the single point.
I have tried using a spherical coordinate system on the constraint positions but to no avail.
Any suggestions on how to constrain the model correctly?
I hope I've explained the problem well enough here but if you want more info then let me know.
I'm using advanced sim in NX8.0.1.5
