+ | ==== Data set description ==== | ||
+ | |||
+ | <note important> | ||
+ | In the data file, each block of data is attributed to a direction (I,J or K).\\ | ||
+ | Each direction can be split in several parts (segments) on which a specific distribution law is applied in order to place the discrete nodes.\\ | ||
+ | Each distribution law is associated to a function defined by a namelist. The available functions are : | ||
+ | * Regular function \\ (Function_name= REGULAR_MESH) | ||
+ | * Hyperbolic tangent function "one side" \\ (Function_Name= TANH_ONE_SIDE_MESH) | ||
+ | * Hyperbolic tangent function "two sides" \\ (Function_Name= TANH_TWO_SIDES_MESH) | ||
+ | * Gauss-Lobatto distribution \\ (Function_Name= GAUSS_LOBATTO_MESH) | ||
+ | * Geometric series "type 1" \\ (Function_Name= GEOMETRIC_SERIE_1_MESH) | ||
+ | * Geometric series "type 2" \\ (Function_Name= GEOMETRIC_SERIE_2_MESH) | ||
+ | |||
+ | These functions get a specific data set : | ||
+ | * Number_of_Cells : Number of cells over the segment (for all functions). | ||
+ | * Length | ||
+ | * Left_Cell_Size | ||
+ | * Right_Cell_Size : Reference size of the cell placed at the right tip of the segment (for hyperbolic function "two sides" and geometric series "Type 1" only) | ||
+ | * Reverse_Ordering : Reverse the ordering of the distribution if set to .true. | ||
+ | * End_of_Block_Data : logical set to .true. to declare the end of a data structure (by default it set to .false. by the program) | ||
