[Libmesh-users] Should I move to FEMSystem?

[Renato P. <re...@gm...>]

Hi

So far I am using the "introduction" style to solve a linear system of
equations.
I attach a assemble function, increment timestep and march.

Things are getting more complex, though.
I'm starting to look into adaptative meshing and non linearity, and
the code is getting sort of dirty.
I can reorganize things, that would help, but I consider rewrite using
FEMSystem.
Does not seem simple, but looks powerful.

Questions:
- Is FEMSystem the best way to move forward?
- Is there any other possibility I should be aware of?

Thanks,
Renato
