Temperature as a function of density, for every cell in the computational domain (ideal MHD case). The simulation using N_Jeans = 32 cells per Jeans length is represented by the blue area, while the red region is for the run with only 16 cells per Jeans length. Each data set is delineated by a solid contour line which outlines the data distributions. The two snapshots were taken at similar evolution times, chosen to be just after the N_Jeans = 16 run has departed from its initial adiabatic track. The dashed lines represent the time evolution of the central (densest) cell inside the mesh (these tracks continue beyond the time of the snapshots to provide a wider context). The black arrow indicates the place where the low-resolution track departs from its original adiabat.
