HIT of a non-reacting flow

This is a very simple DNS computation of a HIT with a constant-properties gas.
The main parameters of the simulation are:

  • temporal integration: RK3,
  • spatial scheme: 4th order skew symmetric
  • no AV.

In this series of computations, the number of cell is increased from 64^3 to 256^3.
