Tariq,
I believe you could solve your problem in a much more elegant way
using one single Triangulation and DoFHandler, specifying the first
dim components of your DoFHandler as your deformation map u, as in x
(t) = x(0) + u(t) for each x in triangulation, t in [0,T], u(0) = 0.
This can be achieved in deal.II using the MappingQEulerian class in
deal.II.
Luca.

Hi,
I am new to deal.ii so maybe the answer to my question is obvious.
I am working on a simulation of a reaction-diffusion-mechanics system.
The general idea is to deform the domain on which the reaction-
diffusion-system lives according to the concentration.
As the equations of finite deformation mechanics get very nasty in
the deformed domain it is convenient to solve them in the undeformed
domain ( in so called material coordinates).
Currently I am trying to realize this using two triangulations which
are initially identical, simulate the reac-diff on a mesh associated
to the first and then transfer the solution to a mesh associated
with the second where the mechanics is solved.
In a second step the vertices of the first mesh will be moved
according to the computed deformation.
My problem is that I need to transfer the solutions between the two
triangulations, and according to the documentation one should not
rely on the assumption that two identical triangulations will be
traversed in the same order by an iterator object.
