Description
Used to generate boundary layer thickness on boundary nodes with specified parameters and default BL/nonBL type definition. *blmesh_2d_input_bl and *blmesh_2d_input_nonbl should be used before calling this command.
Inputs
- base_entity_type
- The type of entities to use for the base to generate BL thickness. Only elems are valid.
- base_mark_id
- The ID of the mark containing the base entities. Valid values are 1 and 2.
- num_layers
- The number of boundary layers to generate.
- first_layer_thickness
- The thickness value of the first layer.
- growth_rate
- The growth rate of the boundary layers.
- core_to_BL_ratio
- Ratio of core mesh to BL thickness, which is used for BL reduction.
- corner_factor
- A dimensionless value used for corner management. The range is 0.1-1.0 for thinner BL thickness, and 1.0-10.0 for thicker BL thickness.
- string_array
- The ID of the string array that contains additional input parameters. The string array
is created using the *createstringarray command. This should always
be set to 1. Valid strings are:
- DefaultBLSelection:
- Default BL/non-BL selection for all boundary edges. Valid values are:
- number_of_strings
- Integer indicating the size (number of strings) in the string array created using *createstringarray.
