I think it is a good idea to keep your code in separate folders from the start. Maybe you could create one folder for PDE algorithms, one folder for the actual data, one for visualization, one for unit tests etc?
Think about the newcomer who just cloned your project. You don't want him to be puzzled what file should he open first. There should be a main.py file together with README.md so that he clearly knows what to open first, then a folder src so that he can say: "OK, when I want to dive into the code details, I should go to src/algorithms. If I want to check the initial data, I should open src/data. OK, there is this test folder, that's where all the unit tests are..."
