The PETSc Vec viewer just plots the real part of the vector.
VecView_Seq_Draw_LG()
to plot the imaginary part or phase etc you would need to write your own
plotter (though you can copy some of the code, for example for
VecView_Seq_Draw_LG())

Hi ,
Does petsc automatically convert complex valued vectors to absolute value
vectors before passing it to a viewer ? Is there a way to view the phase of
a vector ?
Thank You,

Thank you for the explanation. My intent is to define periodicity from gmsh.
With your tip I managed to do that!

Dear Stefano,
Your tip worked.
In order to enable the periodic information in the gmsh file, I need to add:
petsc4py.init('-dm_plex_gmsh_periodic’)
Thanks a lot!

Dear Matt,
Thank you for your quick reply. As for your question: "why would there be a
difference? They should be numbered in the same way.”
I see the degrees of freedom living on the periodic domain as the ones living
at boundaries between interior elements. This is what I expect for non-perio

Dear All,
I having been trying to add periodic domain functionality to my code. I am able

Hi,
sorry I missed the last response.
The system should be index 1 (being not a 100% certain I calculated
everything correct, it can be at most of index 2).
I cannot show the code easily, the code is quite complex (the system arises
from a FEM discretization).
