Computing stucks at 71%

Please login with a confirmed email address before reporting spam

Hi I am now trying to simulate a 3d model for plasmonic response from a cylinder. During computation, it reaches 70% within a minutes or so, but then it stucks there for hours. Could you please suggest me the necessary actions to rectify it.

Thanks Mahfuj

Could be all sorts of kinds of things going on. You might want to try changing to a different solver, different solver settings, different meshing settings, or different discretization of the elements, among other things. Check your mesh quality using mesh, statistics. If mesh quality is very poor in some places, that can play havoc with some of the solvers, and you may have a geometry issue, so take a look at where your various edges and points get near one another. Take a look at any warnings in the log too.
