Namelist "Simulation_Management"
This data setup allows the user to set the time parameters of the code in order to :
- perform the numerical simulation (time step, stopping criteria…)
- record the results associated to time series of probes, instantaneous quantity fields, statistical quantities.
- record the backup/restart files
—–
Restart_Parameter
- 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.
Steady_Flow_Stopping_Criterion_Enabled
- Type : Boolean value
- Activation of the stopping criterion for steady flow (based on the L2-norm of the time variation of quantities).
Steady_Flow_Stopping_Criterion
- Type : Real value
- When the L2-norm of the time variation of quantities is lower than this value, the simulation is stopped and the solution corresponds to a steady flow.
Number_Temporal_Iterations
- Type : Integer value
- This value is the maximum of time iterations performed by the code before stopping.
Final_Time
- Type : Real value
- This value is the physical time limit reached by the simulation before stopping.
