Namelist "Cylindrical_Immersed_Bodies"

This data setup is used to build the cylindrical solid bodies that contribute to the geometrical configuration. The form and the position of each cylinder are defined by means of its height, the axis lengths of its elliptic base and coordinates of the mid-height point.

Full data set of the namelist

In 2D geometrical configurations, only the part related to the base of the 3D-cylinder can be used to build an elliptic form. In this case, the height of the cylinder is zero and the coordinates of the mid-height point coincide with the center of the ellipse. 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 cylinders. Find here some examples about wall boundary conditions.

Definition of the data set

Axis_Direction

Type : real value

This value defines the orientation of the axis with respect to the grid index {I,J,K}. The values 1, 2 and 3 are associated to the I,J and K-direction, respectively.

Default value : none

Xi_Center, Xj_Center, Xk_Center

Type : real value

Coordinates of the mid-height point of the cylinder (in 3D) or the center of the ellipse (in 2D).

Default value : none

Small_Axis_Radius

Type : real value

Half length of the small axis of the elliptic base of the cylinder.

Default value : none

Great_Axis_Radius

Type : real value

Half length of the great axis of the elliptic base of the cylinder.

Default value : none

Identifier_Value

Type : integer value

Identifier related to the rank number of the wall boundary condition setup that is applied to a polyhedral body. If Identifier_Value=3, the polyhedral body is linked with the 3rd wall boundary condition setup written in the data file. A wall boundary condition setup pools the wall boundary conditions applied to the velocity components, heat and species. It can be built from the namelists “Velocity_Wall_Boundary_Condition_Setup”, “Heat_Wall_Boundary_Condition_Setup” and “Species_Wall_Boundary_Condition_Setup” (see some examples here for details).

Default value : none

End_of_Data_Block

Type : boolean value

Specify the end of the namelist or a group of this type of namelist (if true).
