Description
Generates surface meshes using surface deviation parameters with growth ratio transitions given by refinement sizes defined on points, edges and surfaces.
Inputs
- mark_id
- The ID of the mark containing the surfaces to mesh. Valid values are 1 and 2.
- elem_size
- The default element size used to calculate element densities along edges (when necessary).
- elem_type
- Flag indicating the elements generated for mapped meshing algorithms. Valid values are:
- 0 - trias
- 1 - quads
- 2 - mixed
- 3 - right trias
- 4 - quads only
- elem_type_2
- Flag indicating the elements generated for free meshing algorithms. Valid values are:
- 0 - trias
- 1 - quads
- 2 - mixed
- 3 - right trias
- 4 - quads only
- previous_settings
- Flag indicating whether to break, keep or redo connectivity between neighboring
surfaces. Valid values are:
- 0 - Keep previous settings and do not break connectivity between neighboring surfaces.
- 1 - Break connectivity between neighboring surfaces.
- 2 - Keep connectivity between neighboring surfaces.
- 3 - Redo connectivity between neighboring surfaces by expanding surface selection by one layer of adjacent surfaces.
- comp_mode
- Parameter specifying how entities are organized into components:
- 0 - Elements are created in the current component.
- 1 - Elements are created in the same components as their parent surfaces.
- size_control
- Flag indicating whether to create uniformly sized elements. Valid values are:
- 0 - Do not create uniformly sized elements.
- 1 - Create uniformly sized elements.
- skew_control
- Flag indicating whether to create optimally shaped elements when using mapping
algorithms. Valid values are:
- 0 - Do not create optimally shaped elements.
- 1 - Create optimally shaped elements.
- mesh_type
- Parameter specifying the meshing algorithm for edge/surface meshing. Valid values are:
- 34 - Proximity and curvature based surface meshing.
- 35 - Curvature based surfaced meshing.
- 36 - Proximity and curvature based meshing with free edge deviation.
- 37 - Curvature based surface meshing with free edge deviation.
- keep_mesh
- Determines wether any existing mesh is preserved. Valid values are:
- 0 - Do not keep existing mesh.
- 1 - Keep existing mesh.
- min_size
- The minimum edge size.
- max_size
- The maximum edge size.
- chordal_dev
- The chordal deviation value.
- max_angle
- The maximum angle (in degrees) between edges.
- growth_rate
- The growth rate of the refinement size transition.
- id_array
- The ID of the string array that contains the refinement geometry IDs. The integer array is created using the *createarray command. This should always be set to 1.
- number_of_ids
- Integer indicating the size (number of integers) in the integer array created using *createarray.
- size_array
- The ID of the double array that contains the refinement geometry sizes. The double array is created using the *createdoublearray command. This should always be set to 1.
- number_of_sizes
- Integer indicating the size (number of doubles) in the double array created using *createdoublearray.
