Currently, this works for the field methods, and I don't think it works for the particle method. In the test I included, I modified from the composition_passive.prm and prescribed the composition on the left half of the domain. So the left side would stay the same value while the right side is advecting.

t = 0

t = 10

Ideally, I would want a method that works for the particle method. At least that's something I was thinking when creating the PR. However, I feel this is also useful with the field method.

This is great @lhy11009 thanks for this! I only had a few minor comments about cleaning up the test file and the formatting of things, but other then that I think looks great.

Hi @danieldouglas92, Thanks for reviewing my changes.
See my reply on the test file and check the comments I added to the code. Otherwise, I have resolved the conversations.

@lhy11009 the rest of your changes look great! Thanks for addressing them so quickly. If including the cookbook parameter file also causes the model to hang don't worry about it, but I would try adding the include statement to that cookbook file if you haven't already and see what happens.

The code looks all good @lhy11009, and thanks for the reviews @danieldouglas92. I have some minor comments and questions, but the functionality looks all good.
