You need to fully appreciate that consequences of the rigid body assumption and joints. Say for example you are trying to do and over center lock it can't be done because at TDC you will have infinite stiffness and the program aborts with the message you have indicated. Similar things can happen in situations that are not so obvious when you haven't been considering this subtlety. You can replace joints with force based objects with stiffnesses (like a bushing) and then thing will complete. As for why it won't identify the joint.......the message is generated by the ADAMS solver and SWx does not appear to process the message to do that for you. How many cylindrical joints do you have?
spent most of the day trying to find the problem, tried stiffening cylindrical joints but that caused more problems.
I eventually tried dabbing a light damper on two moving beams, and this "fixed" the lock up.
I have not the faintest clue why.
how many redundancies do you have?
Thanks for your reply.
No worries now, all working fine.
No redundancies, no suppressed mates left over, no dodgy or red mates, all cleared out.
I think the assembly just needed some little resistance to work against, somewhere in the structure, just to hold it all together.
I had to use motion analysis to make the video, it refused to animate in animation or basic motion,
probably caused by the constantly changing sliding limit mates on the sliders.
