Description |
Structured line set data structure |
Usage |
Structured_line_set NUM=ival where ival is the data structure number |
Description |
Overview The structured line set data structure is used to define the data relative to selected structured lines. If Number_divisions is specified it will overwrite the default value specified in Structured_mesh_data structure.
|
 | Number_divisions Number of divisions for structured lines (Optional) |
Usage |
||||
|
||||
Description |
||||
Number of divisions for the lines within the Structured_line_set. If specified the default value specified in Structured_mesh_data will be overwritten.
|
| Division_size_ratio Ratio of size of first division to size of last division on line |
Usage |
||||
|
||||
Description |
||||
A non-uniform division distribution on selected lines may be defined using Division_size_ratio. The input value defines the ratio of size of last division on the line to size of first division on line; i.e. if a value of 2 is specified the first element will be length x and the last element length will be 2x, where x is automatically computed from the side length.
Notes •The direction of the line divisions ratio can be reversed for Division_size_ratio by defining the inverse ratio, e.g. instead of 0.2, define ratio as 1/0.2, i.e. 5.0.

| Lines List of structured lines |

Description |
|||||||||||||||
List of lines to be meshed using the specified structured division set. If the division style is defined using either Division_size_ratio or Division_size_distribution the mesh will be sensitive to the direction of the line.
Notes •The direction of the line divisions ratio can be reversed for Division_size_ratio by defining the inverse ratio, e.g. instead of 0.2, define ratio as 1/0.2, i.e. 5.0. •The direction of the line division distribution can be reversed for Division_size_distribution by defining the size distribution in the reverse order.

Description |
|||||||||||||||
The Division_size_distribution dataset allows the specification of specific weights for each division of the line (the division sizes will be computed according to the specified weights). For example a division with weight 2 will have twice the length of a division with weight 1. The data definition has the form: d1, d2 ... dn where di are the weights for each division and n is the number of divisions.
Notes •The direction of the line division distribution can be reversed for Division_size_distribution by defining the size distribution in the reverse order.
