hi,
im running a static research on a human jaw model. the case is, after i set up all the bcs and loads, it start to solved, but it always stop at about 36% for a long time, then it just end up suddenly, and show up a result. i wonder whether this is a normal case, and also i doubt the accuracy of the result, because it looks like an uncompleted work and somehow just end it, has anyone occur the same case?
(the following figure is the exact case of my description)
hello, i think i agree about the mostly time on solving body contacts, cause i got lots of curve from my model(those human bones), anyway, im also wondering perhaps low down the solving precision may help it get over the "contact" part faster, like change another solver(currently using FFEPlus), can be an option or solution for this case. thanks for your reply
Hi Lin, yes you could. The FFEPlus solver is supposed to be more efficient for large scale problems, (>100000 degrees of freedom)
Hope it works well for you.
Kind regards
Prasad
hi Prasad, lots of thank for your comments and suggestions, ill try more, thanks!
Hi, this seems to be common with Simulation studies, I have often had studies "stuck" for a long time at 36 or 27%, then it will suddenly complete.
I believe the longest time in any Simulation study is given to solving the contact conditions and constraints, so it may be that your study is stuck for a long time solving hose, then it completes the rest (forces, fixtures) quickly.
Thanks
Prasad
