Let me tell you that I am a beginner in deal_II. I have a fair idea
about finite element method whereas no idea about c++. While playing
with the tutorial program step-6, and changing the domain to a square
one between (0,1), I find a wrong solution. Whereas, if I change the
domain to a square one between (-1,1) then I get the correct solution.
Since there is no other changes made in the problem, can anyone please
explain this? Does it mean that we always have to use a domain like this
or I am making some mistakes. The solutions are attached herewith.
My question would be: how do you determine whether you have the
correct/wrong solution? What do you compare with?
