Documentation du code de simulation numérique SUNFLUIDH

This data setup is used to define the initial velocity field over the domain.

• Type : real value
• Reference velocity along the I-direction.

• Type : real value
• Reference velocity along the J-direction.

• Type : real value
• Reference velocity along the K-direction.

• Type : integer value
• Option to define the distribution of the I-velocity component over the domain :
  • 0 : Uniform distribution
  • 1 : Parabolic profile along the J-direction. In this case the reference velocity defines the space-averaged velocity.
  • 2 : Parabolic profile along the K-direction. In this case the reference velocity defines the space-averaged velocity.
  • 3 : Inlet profile is spread over the domain (suppose an inflow oriented along the I-direction is defined)

• Type : integer value
• Option to define the distribution of the J-velocity component over the domain :
  • 0 : Uniform distribution
  • 1 : Parabolic profile along the I-direction. In this case the reference velocity defines the space-averaged velocity.
  • 2 : Parabolic profile along the K-direction. In this case the reference velocity defines the space-averaged velocity.
  • 3 : Inlet profile is spread over the domain (suppose an inflow oriented along the J-direction is defined)
  • 4 or greater : Optional values associated to velocity fields defined by the users in the appropriate fortran module (see module_user_define_init_fields.f90). BEWARE : This can involve generally all the velocity components. In this case, the option value associated to the other velocity components can be useless. The reference values can be used to define the velocity scales.

• Type : integer value
• Option to define the distribution of the J-velocity component over the domain :
  • 0 : Uniform distribution
  • 1 : Parabolic profile along the I-direction
  • 2 : Parabolic profile along the J-direction
  • 3 : Inlet profile is spread over the domain (suppose an inflow oriented along the K-direction is defined)

• Type : real value
• Magnitude of the white noise on the I-velocity component.
• The magnitude is defined as a fraction of the local value I-velocity component ( i.e. 0.4 corresponds to 40% of the local velocity component)

• Type : real value
• Magnitude of the white noise on the J-velocity component.

• Magnitude of the white noise on the K-velocity component.
