+ | ==== Timestep_min ==== | ||
+ | * Type : Real value | ||
+ | * Minimum value of the time step. This variable can be omitted when the time step is constant. | ||
+ | ==== Timestep_max ==== | ||
+ | * Type : Real value | ||
+ | * Maximum value of the time step. This variable set the value of the time step when it is constant. | ||
+ | ==== CFL_min ==== | ||
+ | * Type : Real value. This variable can be omitted when the time step is constant. | ||
+ | * Minimum value of the CFL parameter. | ||
+ | ==== CFL_max ==== | ||
+ | * Type : Real value | ||
+ | * Maximum value of the CFL parameter. This variable set the value of the CFL parameter when it is constant. | ||
+ | ==== Iterations_For_Timestep_Linear_Progress ==== | ||
+ | * Type : Integer value | ||
+ | * Number of time iterations over which the CFL parameter or the time step can evolve linearly. When the time step or the CFL parameter are constant, this variable must not set to a value greater than 1. It could actually be omitted (this default value is 1). | ||

+ | * This variable defines the recording rate, __in time units__ , of instantaneous fields (for instance, when " | ||
+ | ==== Start_Time_For_Statistics ==== | ||
+ | * Type : Real value | ||
+ | * Time from which the statistical fields are calculated. | ||
+ | ==== Time_Range_Statistic_Calculation ==== | ||
+ | * Type : Real value | ||
+ | * Time range over which statistical fields are calculated. When this time range has been covered, statistical fields are recorded in a file named rst_xxxxxxx_yyyyy.d (' |
