Dear Daniel,
I am working on a similar problem (planetary acoustic oscillations). I am
interested in looking at your tutorial for an electromagnetic cavity, but
it seems that the pull request was deleted. I wonder if it can be revived.
Thank you,
Anton.

Dear Deal.II community,
I am working on implementing a vector eigenproblem in deal.ii, starting
from the step-36 example. The question I am studying is the normal
oscillation of a fluid planet. The eigenproblem is of this type:
_
Ok, I see - it is that EPS_TARGET_MAGNITUDE flag that was missing. It works
now! Thanks a lot, Simon.
Anton.

Dear All,
I am trying to use a shift-invert transformation in step-36. I did minimal
changes in the solve function adding the following code that describes what
spectral transformation I need to do:
SolverControl solver_control (dof_handler.n_dofs(), 1e-9);
SLEPcWrappers::SolverKrylovSchur eige
Yes, that part now works. Thank you, Wolfgang.
Anton.
