Classic n-body simulation. O(N^2) version. Very simple to implement.
Simulating Martian EDL. What will happen when a spacecraft enters, descends and lands (or crashes) on Mars? We take into account the variation in Martian atmospheric density with altitude. I've used data from paper (page 4/19). Simulation returns various parameters of the spacecraft at a desired point.
How much payload can Starship shuttle b/w the Earth and the Moon? The relationship b/w LEO->Moon payload and Moon->LEO payload is linear and I've shown why.
