Domain_Features

This data setup defines the domain size, the grid data, the domain decomposition features (MPI parallelisation characteristics : number of MPI processes bounded to subdomains and how they are distributed over the domain) and the number of threads also used to split the domain (OpenMP parallelisation).

Geometric_Layout

Type : integer value

This option selects the type of geometry configuration used :

0 : Cartesian geometry

1: Cylindrical geometry. The axis is oriented along the K-direction. The coordinate system is

2: Cylindrical geometry. The axis is oriented along the I-direction. The coordinate system is

3: Cylindrical geometry. The axis is oriented along the J-direction. The coordinate system is

Start_Coordinate_I_Direction

Type : real value

origin coordinate along the I-direction.

Start_Coordinate_J_Direction

Type : real value

origin coordinate along the J-direction.

Start_Coordinate_K_Direction

Type : real value

origin coordinate along the K-direction.

End_Coordinate_I_Direction

Type : real value

End coordinate along the I-direction.

End_Coordinate_J_Direction

Type : real value

End coordinate along the J-direction.

End_Coordinate_K_Direction

Type : real value

End coordinate along the K-direction.

Cells_Number_I_Direction= integer value (Number of cells along the I-direction, excluding the ghost-cells)
Cells_Number_J_Direction= integer value (Number of cells along the J-direction, excluding the ghost-cells)
Cells_Number_K_Direction= integer value (Number of cells along the K-direction, excluding the ghost-cells)

Number_OMP_Threads= integer value (Number of Threads for OpenMP)
MPI_Cartesian_Topology= true (MPI cartesian topolgy) or false
MPI_Graphic_Topology= true (MPI graphic topology) or false
Total_Number_MPI_Processes = integer value (number of MPI processes)
Max_Number_MPI_Proc_I_Direction= integer value (maximum number of MPI processes along the I-direction)
Max_Number_MPI_Proc_J_Direction= integer value (maximum number of MPI processes along the J-direction)
Max_Number_MPI_Proc_K_Direction= integer value (maximum number of MPI processes along the K-direction)

Regular_Mesh= true or false (in this case, the meshgrid must be built with the sotfware meshgen)
