| * 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). | * 1 or 2 : The simulation is resumed from a temporary backup file recorded during the previous simulation.

| * 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. | * 3 : The simulation is resumed from the last backup file built during the last time step of the previous simulation.

| + | * Type : Real value | ||
| + | * This value is the physical time limit reached by the simulation before stopping. | ||
