Hi Lorenzo,
What an interesting coincidence - I saw a student show me the same error
message last week. This is definitely a bug in deal.II!

I would still want to initialise my solution vector to the values which are
prescribed at the boundary before solving.
Context:
I am solving a nonlinear problem with DG and my BCs are in the weak form.
It would be helpful if I start with a solution vector that is closer to the
prescribed
I also would like to point out that make test did not spot any problem

Dear Wolfgang,
thanks for clearing this up and responding so fast. Your explanation makes
sense to me.

Only if I uncomment line 30 of my code (// , mapping(mapping_degree)) the
program compiles. Why is that? In my understanding, the program should compile
just fine without the initialization of the mapping member variable since
there is no requirement
Hi,
I've recently used the following function for a similar task:

(see in particular the first snippet). This works under the assumption that
the cartesian grid is

Do you need to use Boost in your own project? If you don't, try adding
-DDEAL_II_FORCE_BUNDLED_BOOST=ON to your configuration.

Dear all,
I am fairly new to deal.ii and have a question concerning the
MappingQ-class of deal.ii
Why do I have to initialize the private mapping member of type
MappingQ to get a compilable code? To illustrated what I mean, I did
thin out the step-11 tutorial in the following way:
#include
I am halfway there, after taking Wolfgang's correction. Now the program is
running, but runs into trouble later with error:
