Gravity is computed with the TreePM algorithm at expansion order p=3. Three output times are defined, for which FOF group finding is enabled, and power spectra are computed as well for the snapshots that are produced. Also, the code is asked to compute a power spectrum for each output.

**C) `Blob Test`**
The blob test consists in the simulation of a spherical cloud (blob) that is placed in a wind tunnel in pressure equilibrium with the surrounding medium. The cloud has a temperature and a density 10 times lower and higher, respectively, than the surrounding medium. This test allows for the development of hydrodynamical instabilities at the cloud surface, e.g. Kelvin-Helmholtz and Rayleigh-Taylor, leading to the cloud breakup with time. The cloud is setup with 1 million smooth particle hydrodynamics (SPH) particles. A more sizeable test is done with 10 million particles.
