Description

Meshes a selection of surfaces using saved or default parameters and various options.

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:

• 1 - Standard edge meshing.
• 2 - Chordal deviation edge meshing.
• 3 - Proximity based surface meshing.
• 4 - Proximity and curvature based surface meshing.
• 5 - Curvature based surfaced meshing.
• 6 - Proximity and curvature based meshing with free edge deviation.
• 7 - Curvature based surface meshing with free edge deviation.
• 11 - Standard edge meshing with flow "align" control.
• 12 - Chordal deviation edge meshing with flow "align" control.
• 14 - Standard edge meshing with flow "align" and "size" control.

min_size

The minimum edge size for chordal deviation meshing. Ignored otherwise.

max_size

The maximum edge size for chordal deviation meshing. Ignored otherwise.

chordal_dev

The chordal deviation value for chordal deviation meshing. Ignored otherwise.

max_angle

The maximum angle (in degrees) between edges for chordal deviation meshing. Ignored otherwise.
