automatically terminating an analysis?
automatically terminating an analysis?
(OP)
Hi there,
I wonder if anyone can help? I'm trying to find a way of getting an analysis to terminate anutomatically when a spring element is crushed to a predetermined strain / displacement. I guess its along the lines of specifying some sort of constraint between the reference nodes of the spring but i can't seem to find a way of doing this and also i have no experience of using an automatic termination command.
Any advice greatly appreciated.
Thanks,
m.

RE: automatically terminating an analysis?
I do not know if there is any such command. But an easy way to do this would be to run a preliminary analysis and find out approximate loads etc at which you get in the neighbourhood of required spring displacement. Then you can refine your analysis around that point.

You can call them from another user subroutine such as UVARM where you can access any user variable.

Good luck.
btw saw your request a day or two ago and didn't have immediate answer. I'm presently helping someone (paid work!) and alighted upon XIT and XPLB_EXIT which I've never used before.
