Type

Description

Re-meshes a selection of surfaces using saved or default parameters and various options, and deletes any elements already meshed on those surfaces.

Inputs

mark_id

The ID of the mark containing the surfaces to re-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.
