*blmesh_2d_computeblthickness
Generates boundary layer thickness on boundary nodes, with specified parameters.
Syntax
*blmesh_2d_computeblthickness base_entity_type base_mark_id num_layers first_layer_thickness growth_rate core_to_BL_ratio corner_factor
Type

Description
Specifies non-boundary layer input for *bl_mesh2d2 and *bl_mesh2d_computeblthickness.
If *blmesh_2d_input_nonbl is not called before *blmesh_2d2, then all edges of the selected region are considered as boundary layer edges.
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.
