[Getdp] Electromagnetic 3D model - Crash info (bug?)

[Lars Rindorf]

Hi Lucas
 
You need to tell getdp the specific name of your domain. I.e. you should set

Group {
  Domain = Region[4000];
}
instead of 
Group {
  Domain = Region[All];
}
 
I'm also working on 3D electromagnetic bloch simulations, and I can help you if have questions.
 
Are you work on band structure calc of photonic crystals?
 
Kind regards
Lars

Hi all,

I've just started working with GetPD and I'm not sure I'm doing the right thing here.
The attached files should solve an 3D eigenvalue EM problem (no boundary conditions or
sources yet) but I can't seem to make them work:

getdp test -solve EMW_3D_Eigen -pos EMW_3D_Eigen

Loading   : Problem definition 'em\test.pro'
Loading   : Problem definition 'em\em.pro'
Info      : Selected Resolution 'EMW_3D_Eigen'
Loading   : Geometric data 'em\test.msh'
Info      : System 'A' : Complex, Frequency = 0 Hz
P r e - P r o c e s s i n g . . .
Operation : Treatment Formulation 'EMW_3D_Eigen'
Error     : Segmentation violation (invalid memory reference)
            ------------------------------------------------------
            You have discovered a bug in GetDP! You may report it
            by e-mail (together with any helpful data permitting to
            reproduce it) to <getdp at geuz.org>

The geometry file is transfinite just cause I plan to use Bloch periodic conditions later (any
help in that matter would also be welcome).

If I can manage to understand how to correctly create a model in GetDP, I would say it's one
of the best sw packages for FEM, but I couldn't do it following only the documentation.

Thanks for any help,
Lucas
