Documentation du code de simulation numérique SUNFLUIDH

This data setup allows the user to set the time parameters of the code in order to :

• perform the numerical simulation (time step, time range, …)
• record the results associated to time series of probes, instantaneous quantity fields, statistical quantities.
• record the bacup/restart files

• Type : Integer Value
• This data indicates how is initialized the simulation :
  • 0 : The simulation starts from the beginning corresponding to an initialization state.
  • 1 or 2 : The simulation is resumed from a temporary backup file recorded during the previous simulation. Useful to resume a simulation suddenly interrupted. As the temporary backup file a regularly removed during a simulation, only the two last files created by the code are available. They correspond to the number 1 or 2. The number of last file created is recorded in the file num_sav_xxxxx.d (xxxxx correspond to the MPI process number when the simulation is performed in a domain decomposition approach).
  • 3 : The simulation is resumed from the last backup file built during the last time step of the previous simulation. Useful to continue a incompleted simulation. The number 3 must be present in the file num_sav_xxxxx.d (proof that the previous simulation is correctly completed), otherwise the numbers 0, 1 or 2 (related to the previous cases) will be present.
