Namelist "Polyhedral_Immersed_Bodies"

This data setup is used to build the polyhedral solid bodies that contribute to the geometrical configuration. The form and the position of each polyhedron are defined by means of its corners (4 in 2D and 8 in 3D).
Each corner is located by a couple of coordinate {Xi_n,Xj_n} in 2D or a triplet of coordinate {Xi_n,Xj_n,Xk_n} in 3D, where the index n is the corner number.
Each corner is numbered as following :

from n=1 to n=4, the group of corners forms a quadrangle that is the floor of the polyhedron in 3D (or directly the solid body in 2D). The corner's number must be ranked in the counterclockwise direction and the corner n=1 must be the one with the lowest values.

from n=5 to n=8, the group of corners forms a quadrangle that is the ceiling of the polyhedron. The rules applied to sort the corners are the same as previously. This group can be omitted in 2D configuration.

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 define several type of boundary conditions.

Xi_1, Xj_1, Xk_1

Type : real value

Coordinates of the 1st corner (that belongs to the floor of the polyhedron). For 2D configurations, only the couple {Xi_1, Xj_1} could be considered. This coordinate set must get the lowest values of the floor group.

Xi_2, Xj_2, Xk_2

Type : real value

Coordinates of the 2nd corner (that belongs to the floor of the polyhedron).

Xi_3, Xj_3, Xk_3

Type : real value

Coordinates of the 3rd corner (that belongs to the floor of the polyhedron).

Xi_4, Xj_4, Xk_4

Type : real value

Coordinates of the 4th corner(that belongs to the floor of the polyhedron).

Xi_5, Xj_5, Xk_5

Type : real value

Coordinates of the 5h corner (that belongs to the ceiling of the polyhedron). This coordinate set must get the lowest values of the ceiling group.

Xi_6, Xj_6, Xk_6

Type : real value

Coordinates of the 6th corner (that belongs to the ceiling of the polyhedron).

Xi_7, Xj_7, Xk_7

Type : real value

Coordinates of the 7th corner.

Xi_8, Xj_8, Xk_8

Type : real value

Coordinates of the 8th corner.
