Hello Stephen,
since you are dealing with the union of two triangulations, you could
iterate over the fine triangulation and identify the cells on the
coarser triangulations, which cover the fine cell. Then you can build
FEValues objects on both triangulations and evaluate the solution vector
at the quadrature points and do some projection, which fits to your
finite element.
Best Regards,
Markus

Hi,
I am currently dealing with a time based problem and given the mesh at
the old time step and one at the current time step, need to project a
finite element function from either of those two meshes to a new one
which is the union of both meshes. I can get the DoFHandlers etc to
work on this union triangulation but when I cannot see how to do
this... basically I want something like SolutionTransfer (which works
nicely btw!) which would allow me to project between the different
meshes. Any help is appreciated.
Thanks,
Stephen
