# # [Rising Thermal Bubble](@id EX-RTB-docs)
# In this example, we demonstrate the usage of the `ClimateMachine`
# [AtmosModel](@ref AtmosModel-docs) machinery to solve the fluid
# dynamics of a thermal perturbation in a neutrally stratified background state
# defined by its uniform potential temperature. We solve a flow in a
# [`FlatOrientation`](@ref LESConfig) (Box) configuration - this is
# representative of a large-eddy simulation. Several versions of the problem
# setup may be found in literature, but the general idea is to examine the
# vertical ascent of a thermal _bubble_ (we can interpret these as simple

Final Blog

This blog marks end of a really wonderful experience with amazing people! Special shoutout to Chris Rackauckas, Yingbo Ma and David Widmann who immensely helped me in getting my work done and helping me throughout this whole summer. I would always be greatful to them for accepting me as a student.

Regarding my work, my project dealt with more of general fixes for many of the JuliaDiffEq repositories. My work was focussed the most on Callbacks, Non Linear solvers and other Derivative utilities. It involved a lot of moving code back and forth from one repository to another as we were making the common tools in all the repositories shifted to DiffEqBase. Also I made a small benchmarking service called DiffEqBot for the organization which also got featured on JuliaLang Blog! Below is the list of my contribution grouped by the type of work -

Derivative Utilities and Non linear solvers

We used to have seperate copies of the NLSolver methods in each of the repositories. All of them were basicall


Hello @DiffEqBot!

Hi! Today we all got a new member to the DiffEq family. Say Hi to our own DiffEqBot - A Bot which helps run benchmarks and compares with the current master of a given package. It also generates and stores the Reports generated in a repository. What's special about this is that it is completely stateless (no databases involved at all, just juggling between repositories!) and it has no exposed public URLs. Even though highly inspired by Nanosoldier, this has a completely unique workflow.

How do you make it work?

So what all you need to do is call @DiffEqBot runbenchmarks in a comment in a PR of a JuliaDiffEq repository and it will do all the work for you. It will benchmark your pull request against the current master and post the link of report when the job gets completed. Found a bug in PR and now you don't need to complete previous job? Just comment @DiffEqBot abort and it won't run now. You also need to mai
