[Getdp] Available details on external PETSc errors happening in GetDP ?

[Christophe Geuzaine]

Dear Guillaume,

Reduce the tolerance on the nonlinear residual, e.g. from 1e-6 to 1e-12, and you should be ok. (Beware that the scaling of the current density in your post-processing seems wrong: it should be multiplied by ScalingFactor^2.)

Would it be interesting to customize the example on the wiki to handle such tapes? If so, what would be a good geometry? (I guess a single tape is a bit to simple?) Is there a non-superconduting material around such tapes? Or are they, as in your example, directly surrounded by insulators?

The enclosed GetDP model generate systematically such an error at $Time = 0.0018 s ($TimeStep = 180), non-linear iteration 13. Is it possible to have more details on the issue, maybe by raising GetDP’s verbosity level ? Or should I download the source code and recompile it with debug options activated enable to understand what happened ? I do not know what to deduce from the fact that the error can be reproduced… Other than that, I would greatly appreciate if someone could explain me why the current density Jz in the enclosed .res file has a strong irregularity where the cut in the air made by the cohomology solver meets the boundary of the superconductor. Thank you in advance,
