Documentation du code de simulation numérique SUNFLUIDH

This data setup are used to define the inflow condition features. The inflow geometry is restricted to rectangular/line forms in 3D/2D configuration. In the particular case of cylindrical geometries, the outlets can be circular, annular or bowed retangular. In fact, the geometry of the outlet fits the grid topology.
Whatever the grid topology, the orientation and the span of the inflow are defined by means of :

• the normal vector of the outlet plane associated to a specific direction (I,J or K)
• the coordinates associated to the position of the outlet sides along the two perpendicular directions to the normal vector (denoted the first and second span directions).
  

When the normal vector is oriented along the I-direction, the first span direction is J and the second is K.
When the the normal vector is oriented along the J-direction, the first span direction is I and the second is K.
When the the normal vector is oriented along the K-direction, the first span direction is I and the second is J.
Don't forget to set the boolean data “End_of_Data_Block” at the end of the namelist. A “.true.” value means the end of the data block when several namelists are used to create several outlets.

• Type : String of 6 characters
• Name to define the outflow boundary conditions type. Only one kind of outlet boundary condition is defined at present (Dirichlet type) and the associated name is “INLET”.

• Type : integer value
• This data defines the orientation of the normal vector the outlet in respect with the grid {I,J,K}. The values 1, 2 or 3 point the I, J or K-direction, respectively.

• Type: real value
• Coordinate of the position of the outlet plan along the normal direction previously defined.

• Type : real value
• This coordinate defines the lower side of the outlet plan span along “the first direction” (see the note above).

• Type : real value
• This coordinate defines the upper side of the outlet plan span along “the first direction” (see the note above).

• Type : real value
• This coordinate defines the lower side of the outlet plan span along “the second direction” (see the note above).

• Type : real value
• This coordinate defines the upper side of the outlet plan span along “the second direction” (see the note above).

=

• Type : boolean value
• Specify the end of the namelist or a group of this type of namelist (if true).
