发帖数: 38 | 1 Hi every Ansys daxia,
I ran into a problem with using Ansys, I am checking my calculations with
Ansys on a thermal problem with radiation boundary condition. However, it
won't converge. Does anybody have experience on similar problem? I apprieciate
very much if daxia can suggest something on how to improve convergence in
nonlinear analysis.thanks a lot. |

发帖数: 1240 | 2 unconvgered solutions are case by case
even a small typo could cause the whole problem
no one can help you this way
maybe you should post your original code here

发帖数: 38 | 3 I don't understand. I didn't write a code. I am using Ansys. sorry I am not
very familiar with Ansys, can daxia give an example like what I can post here
for any suggestions?

normally advanced ANSYS user will rewrite the input file manually
it's more clear and easy to control
GUI of ANSYS sucks

发帖数: 38 | 5 I got it, however it is long, I don't know whether it is appropriate to post
it here. actually, my problem is simple : a 3D rectangular bar with
temperature fixed at both ends and current passing through it to generate
heat. the main problem is the radiation boundary condition, it bring the
nonliearity into this problem. I don't have much experience in using Ansys
nonlinear solver options and radiation options. Does daxia have any
suggestions,like very common ones in dealing with them?
not
