Default: 4
- --boundary_layers_surface_ids <list>
- Comma separated list of surface references to be used to grow layer.
+ --boundary_layer_size_mode <mode>
+ Sets the behavior for the boundary layer sizes.
+ If <mode> is:
+ global: the boundary_layer_global_initial_height is used to compute
+ the layer heights
+ local: the boundary_layer_surface_tags and
+ boundary_layer_initial_height_on_surface_tags are used to compute
+ the layer heights
+ Default: global
+
+ --number_of_boundary_layers <number>
+ Sets the number of boundary layers.
+ Default: 0
+
+ --boundary_layer_global_initial_height <height>

+ --boundary_layer_imprint_tags <list>
Comma separated list of surface references that are imprinted by
boundary layers.
- --boundary_layers_subdomain_direction <dir>
- Describes whether the layers grow inwards or outwards.
- if <dir> is:
- 1 : means the layers grow inward
- -1 : means the layers grow outward
- Default: 1
+ --boundary_layer_geometric_progression <real>
+ Sets the geometric progression for all the boundary layer growths
+ (position of layer number i is h * g^(i-1)).
+ Default: 1.0
- --height_of_the_first_layer <height>
- Sets the height of the first layer.
+ --boundary_layer_max_element_angle <size>
+ Sets the maximum internal angles of elements (in degree). This
+ setting applies to the boundary layer elements only.
+ Default: 165.
- --number_of_boundary_layers <number>
- Sets the number of boundary layers.
+ --normal_direction <dir>
+ Specifies whether mg-hybrid should use the surface normals or the
+ inverse of the surface normals.
+ if <dir> is:
+ 1 : means the layers grow in the same direction as the normals to
+ the surface
+ -1 : means the layers grow in the opposite direction to the normals
+ of the surface
Default: 1
- --boundary_layers_geometric_progression <real>
- Sets the geometric progression for the boundary layer growth (layer
- number i position is i * h * g^i).
- Default: 1.0
-
--gradation <real>
- Sets the gradation for the boundary layer height.
+ Sets the desired maximum ratio between 2 adjacent edges. It applies
+ only to the edges which belong to the tetrahedra.
Default: 2.0
--element_generation <type>
Sets the element type for the mesh generation.
If <type> is:
- tetra-dominant : prismatic or hexahedral elements in the boundary
- layers, tetrahedra in the remaining volume
- hexa-dominant : prismatic or hexahedral elements in the boundary
- layers, hexcore in the remaining volume
- Default: tetra-dominant
+ tetra_dominant : prismatic or hexahedral elements in the boundary
+ layers, tetrahedra in the remaining volume
+ hexa_dominant : prismatic or hexahedral elements in the boundary
+ layers, mixture of hexahedra and tetrahedra in the remaining
+ volume
+ cartesian_core : cartesian hexa core with tetrahedra and pyramids
+ in the remaining volume
+ extrusion_only : only prismatic or hexahedral elements near the
+ boundary are generated. The remaining volume is not filled.
+ Default: tetra_dominant
--collision_mode <mode>
Sets the behavior in case of collision between layers.
If <mode> is:
- decrease : keep the number of desired layer but decrease the height
- of the layers to avoid collision
- stop : stop locally the layers generation; the number of desired
- layer may not be respected
- Default: skip
+ decrease : keeps the number of desired layer but decreases the
+ height of the layers to avoid any collision
+ stop : stops locally the generation of layers to avoid collisions;
+ the number of generated layers may differ from the specified
+ desired number
+ Default: stop
--add_multinormals <yes|no>
Add extra normals at opening ridges and corners.
Default: no
- --multinormals_angle_threshold <angle>
- Set the maximum angle between the multiple normals at opening ridges
- .
+ --multinormal_angle_threshold <angle>
+ Set the maximum angle between the multiple normals at opening ridges.
Default: 30
--smooth_normals <yes|no>
Smooth normals at closed ridges and corners.
Default: no
