Re: [Libmesh-users] ImplicitSystem::get_linear_solver()

[Manav B. <bha...@gm...>]

I see. 

So, I am defining a class that inherits from nonlinear_implicit_system, and calling  get_linear_solver() on that.  This gets to the implementation in implicit_system, since the nonlinear_implicit_system does not define an overriding function. 

Instead, there is one defined in  linear_implicit_system, but that is a different code path.
