In recent years, the problem of space debris has become relevant and is now being studied to reduce the impact that has on the population. For this purpose, at the von Karman Institute for Fluid Dynamics, the project DSMCFED aims to develop a toolset to analyze the re-entry phase of spacecraft during their disposal. The main objective is to simulate the spacecraft fragmentation during the de- scent into the atmosphere by coupling high-fidelity tools to analyze the aerothermo- dynamics, the trajectory, and the thermo-structural response. In this context, to compute the trajectory of the objects it is necessary to evaluate their aerodynamic coefficients at different altitudes, so a code to study the flow interaction with the body is needed.
