During this internship, you will be responsible for implementing a battery of tests on channels with speed imbalance. Initially, in order to become familiar with FLICA5, it will be a question of testing 1D analytical solutions on a single channel. Secondly, we can focus on more complex cases in 2D and with 2 channels. Each test will result in the writing of a Jupyter sheet, with an introduction of the physical context and a restitution of the results in the form of graphs.
