Documentation du code de simulation numérique SUNFLUIDH

This data set allows the user

• to define the precision (simple or double) on the data related to the instantaneous fields and the statistical fields.
• to reduce the dimension of the statistical fields in order to get a profile along a given direction. The reduction is made by space averaging over the other directions.

• Type : Integer Value
  • 1 : Instantaneous fields are recorded in single precision (r4).
  • 2 : Instantaneous fields are recorded in double precision (r8).

• Type : Integer Value
  • 1 : Statistical fields are recorded in single precision (r4).
  • 2 : Statistical fields are recorded in double precision (r8).

• Type : Boolean value
  • .true. : For any quantity f, the statistical computation yields : $$ \overline{f(x,y,z)}= \frac{1}{T}\int_{0}^{T} f(x,y,z,t) dt$$
  • .false. : For any quantity f, the statistical computation yields : $$ \overline{f(x,y,z)}= \frac{1}{N_t}\sum_{n=0}^{n=N_t} f(x,y,z,n) $$ where $N_t$ is number of instantaneous fields considered for the computation.

• Type : characters
• This data defines the direction(s) along which a spatial average is computed in addition of time or sample mean
  • 0 : Statistical fields are not reduced in a profile along a specific direction.
  • 1 : The profile is calculated along the I-direction.
  • 2 : The profile is calculated along the J-direction.
  • 3 : The profile is calculated along the K-direction.
