I have warning notice "negative root in a quadratic equation" while I am solving model under Arc Length Control method. I am still able to get the results without any errors but not quite sure if I can rely on these results because it seems solution time is really short than anticipated. Someone have any idea what's wrong with model?
Thanks Jared.
After setting up completion parameters, I'm able to run the study without any warnings/errors but the response graph looks little weird (copy attached). Initially it goes up to load factor 6.17 but finally getting the expected load factor of 4.8. How can I interpret these results?
not sure, looks weird to me, i'd probably send to support
you might be able to get some more arc steps in there to try and prevent that, thats the only thing i can think of
there is a swx kb article on this error message, customerportal.solidworks.com, it also has recommendations on resolving it
basic answer is that the completion parameters may not be set correclty
