[Libmesh-users] Starting out with libmesh

[Jorge L. <jor...@gm...>]

Hi everyone,

So I am trying to start using libmesh and I have quite some questions that
might be easy to be given suggestions by more experienced people.

1) Understanding the structure of the documentation: It is highly
non-trivial to browse through that. I'm going to describe my problem and
ask you to direct me to several relevant structures for me to get familiar
with.

2) The problem I want to tackle is a combination of the Poisson equation
and the Heat Equation.
For a given time step we solve
\nabla V = Source
and use this to evolve to evolve the Heat-like equation
i \partial \phi / \partial t = f(\phi, \phi', \phi'') + V \phi
where \phi is a complex function, naturally.

3) I noted that libmesh has the 2 problems solved separately in
examples/introduction/introduction_ex4 and somewhere in fem_systems. If
this is useful, I'd have my problem half solved.

All I'm looking for is some guidelines on how to start tackling the problem
with my moderate knowledge of C++ and enormous difficulty in browsing
through the documentation.

Thank you all for your help in advance,
