Georgios,
Thanks for your reply! Essentially what I was trying to do is patch together
two product spaces: ([H1_0]^2, L^2_0) in one part of the domain and
([H1_0]^2, L^2_0) in another, with an interface condition to ensure
solvability for my problem (Stokes in one part of the domain, laplac
Hi everyone
I am trying to implement a template Dirac delta function, which takes a
source vector and its associated DoFHandler, then interpolates the source
vector onto an arbitrary point. Different from VectorTools::point_value,
the target point does not have to be in the source grid. Instead

Dear Time,
Thank you very much! I've been using the preconditioned CG solver that
came with the tutorial thus far. I'll have a crack with GMRES.
Kind regards,
Georgios

I wanted to try the combination of deal.II with complex values (according
to github the integration should be done, if I remember correctly), thus I
compiled PETSC with complex values. Now deal.II told me that step-17 and
step-18 (among others) will not work. Based on my knowledge of the math,
