have never seen that error or run into that limitation. Have you checked the swx kb? Version and sp?
can you confirm it runs with each one individually?
and just to be clear, it isn't a curve for x y and Z for each location, just for the force. ie 2 forces, not 6?
I have not checked the knowledge base as I don't have access to it at the moment. I need find out the license code I think. I am using 2012. Not sure what you mean by sp.
I have run one of them individually without issue. Will try running all of them individually in the future, but that did not appear to be the issue.
There is a curve for each x,y, and z forces so there are 6 forces. Potentially I could convert them to vector form, but I would have to figure out a way to account for the direction within the time curve. Even then though it seems like I would run into the same issue since I would have two time curves instead of one.
if you're on 2012 you may not have access to the kb because it is for subscription service customers only. also i may not have seen the issue because we're using 2013/2014 and 2015. sp is service pack.
once you've confirmed each one runs, update the thread. if they don't all run individually that may be why there is an issue.
in the end if you've defined it that way and it gives you an error, it may just be a limitation. i don't have 2012 to check but if you want post an example i can check if 2015 solves it.
