The procedure of performing in situ analysis with libyt and the API related to each step. These steps must be followed in every round of the analysis. Note that the simulation parameters (e.g., current time), grid distribution (e.g., with AMR), and particles associated with each grid can change during simulation runtime; therefore, they are reset at the end of each simulation iteration. Some entry points (e.g., Python prompt and Jupyter kernel) may be unavailable based on the compilation options.
