-h --help
prints this help.
-v --verbose <verbose>
Sets the verbosity level parameter.
The <verbose> parameter must be in the range 0 to 10:
0 : no detail
10 : very detailed
Default: 3
-i --in <filein>
Sets the input file.
(MANDATORY)
-o --out <fileout>
Sets the output file.
If unset, _hybrid is appended to the input file basename.
Using an existing file is forbidden.
Using the same file as --in is forbidden.
--global_physical_size <size>
Sets the global physical size.
Default: no default.
--max_number_of_threads <maxthreads>
Sets the maximum number of threads to be used in parallel.
Default: 4
--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>
Sets the height of the first layer.
--boundary_layer_surface_tags <list>
Comma separated list of surface references to be used to grow
boundary layers.
--boundary_layer_initial_height_on_surface_tags <list>
Comma separated list of initial heights to be used to grow boundary
layers.
--boundary_layer_imprint_tags <list>
Comma separated list of surface references that are imprinted by
boundary layers.
--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
--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.
--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
--gradation <real>
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, 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 : 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
--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
--optimisation <type>
sets the optimisation type.
If <type> is:
no : no optimisation is applied
yes : optimisation is performed upon mesh generation
only : only optimisation is performed to an existing volume mesh.
Default: yes.

Verbose level - to choose verbosity level in the range from 0 to 10.
HYBRID algorithm mesh layers on groups of faces. If Mesh layers on all wrap is checked, all wrap is meshed as layers (as boundary_layers_surface_ids 5), else only submeshes selected an added are meshed as layers (as boundary_layers_surface_ids 6). Pay attention: theses groups should be defined into the shell mesh from a previous group defined in the geometry.
In case of a mesh based on geometry, if Mesh layers on all wrap on Layers meshes tab is unchecked, you can specify geometrical faces on which boundary layers should be constructed. After clicking Selection button (arrow) you can select faces either in the Viewer or in the Object Browser. Add button adds IDs of the selected faces to the Face IDs list. Remove button removes selected IDs from the list.
