It involved reading a bunch of papers on dynamic subgrid scale modeling (LES turbulence modeling), understanding a big piece of code written by someone else and changing (also adding new features) it to C++, which I didn't know much of until I started working on this project. | ||
The complexity of the code and poor documentation, made it quite challenging to add new pieces of code that worked in sync with the rest of it. It taught me the value of having a clear plan of action before implementation and the importance of testing vigorously. I found it useful at times to discuss certain aspects with more experienced users and refining my thought process. | The complexity of the code and poor documentation, made it quite challenging to add new pieces of code that worked in sync with the rest of it.

I | Octave community does a lot of numerical stuff that I'm interested in. I enjoy code development that centers around math and Octave offers me that. I like the openness and collaboration culture of open-source world. I will definitely continue to contribute irrespective of whether I get selected or not. | ||

Yes, I | Yes, I chose to implement the IBVP for parabolic-elliptic PDEs in 1D and improve ode15s. Besides being compatible with Matlab's pdepe function, I want to make sure it has comparable performance too. | ||

I' | I'll know the source code and community better by getting more involved in help-forums, IRC, etc. I will discuss the frequency and means of communication with my mentor. I have set up a blog to put my weekly/fortnightly progress. This project is more math-intensive than coding-intensive, so I'll use this time to solidify the theory behind implementation well. <br> | ||
