3910. By Adam Candy on 2012-04-26

Chnaged lots of things, made it work and then broke it.
Needs attention.

3909. By Adam Candy on 2012-04-24

Calculate primitives in preparation for the formation of p^star and hence, the added diffusivity.

3908. By Adam Candy on 2012-04-24

Tidied up debugging statements.

3907. By Adam Candy on 2012-04-24

Esured tracer_iterated is initialised correctly (to t, and hence t_old) and also fixed the output of the residual after one iteration (into NonLinPG_Diffusion).
A run on the top hat shows the contribution made by the time derivative (which has a zero contribution in the first iteration) on top of the contribution from the advective term (visible in the first iteration residual dump).

3906. By Adam Candy on 2012-04-24

Sorted out non linear iterations. Routines now dump result after one iteration into the NonLinPG_Diffusivity field, and the end result into Standard_Residual.

3905. By Adam Candy on 2012-03-30

Nonlinear iteration loop nearly there.

3904. By Adam Candy on 2012-03-30

Development of nonlinear loop

3903. By Adam Candy on 2012-03-21

Introduce non-linear iteration option and collect from state (possibly in the wrong place).
Need to now think about the various values of the tracer and updates to it.

Note this commit introduces changes to a test case flml, which we might want to revert in the future.

3902. By Adam Candy on 2012-03-21

Passes dt into the new non-linear PG routine.

3901. By Adam Candy on 2012-03-21

Missed some additions that should have been in the previous commit.
