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.

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 how to construct the wall boundary conditions and some examples.

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

Wall_BC_DataSetName

Type : character string

Name of the wall boundary condition set associated with the body. The wall boundary condition sets are built by means of the namelists Heat_Wall_Boundary_Condition_Setup (Heat boundary conditions) , Velocity_Wall_Boundary_Condition_Setup (Velocity boundary conditions) and Species_Wall_Boundary_Condition_Setup (species boundary conditions), used in regard to the type of problem. The user finds here some examples about wall boundary conditions).

Default value= none
