All ic_hex commands are used as a simple string without argument grouping. If an argument is grouped with curly braces, quotes, or square brackets, an eval should be placed before the command to remove one level of grouping.

Wherever an index range is needed as an argument, only specify the ranges which are limiting indices, not fully displayed indices. For example, for a box with max indices of 3 in i, j, and k (including VORFN), if only j and k are constrained, this argument may look like this: 0:2,3 2:1,3. The 1 index is not specified because it is not limited.

Use [range_string] to return the current active index range.

Wherever a list of volume parts is needed as an argument, [volume_activename_string] can be substituted for the current active parts that contain blocks. For example, the following command returns all visible vertex numbers:

eval ic_hex_select_nodes 1 all [range_string] m [volume_activename_string] node_numbers

Usage: ic_hex_match_and_link_edgesfrom_edgeto_edge

from_edge is the reference edge, to_edge is the target edge(s).

ic_hex_copy_edge_params from to absolut [0] no_nodes [0]

Allows you to copy the edge parameters from a reference edge to the selected edge(s) or to all parallel edges.

Usage: ic_hex_copy_edge_paramsfrom_edgeto_edgeabsolutno_nodes

from_edge is the reference edge. to_edge could be a list of selected edges or the value copy_to_parallel. absolut indicates that the exact spacing will be copied (default 0). no_nodes determines whether the number of nodes will be copied (default 0).

ic_hex_ratio_check_minquality which fams [""] range [""] project_type [2] full [0]

Checks and returns the minimum quality ratio (in case of "Volume change" the maximum quality).

Usage: ic_hex_ratio_check_minquality "criterion" [parts to check] [index range] [project_type 2]

ic_hex_scale_mesh_size_with_spacings_gui scale fams [""] range [""] use_output_blocks [0]

Scales the mesh size and edge spacing1, spacing2, and max space. This automatically selects all visible edges.

Usage: ic_hex_scale_mesh_size_with_spacings_guiscale_factor [parts] [index range] [use_output_blocks 0]

ic_hex_scale_mesh_size_with_spacings scale edges

Scales the mesh size and edge spacing1, spacing2, and max space.

Usage: ic_hex_scale_mesh_size_with_spacingsscale_factoredges_to_scale

ic_hex _get_edge_segment_number args

Usage: ic_hex_get_edge_segment_numberedge_vertex1edge_vertex2

ic_hex_get_hidden_nodes args

Returns also the hidden nodes (if any) of an edge. Usage: ic_hex_get_hidden_nodesedge_vertex1edge_vertex2

ic_hex_set_unstruct_face_method args

Sets the method of mesh for unstructured 2D blocks.

Usage: ic_hex_unstruct_face_methodmethod

Method can be uniform_quad, gambit_pave, or auto.

ic_hex_ogrid_smooth_transition args

Turns the Ogrid_smooth_transition option on or off.

Usage: ic_hex_ogrid_smooth_transition [on/off]

Returns 0 (off) or 1 (on): set state [ic_hex_ogrid_smooth_transition]

ic_hex_project_to_topo args

Turns the Project_to_topo option on or off.

Usage: ic_hex_project_to_topo [on/off]

Returns 0 (off) or 1 (on): set state [ic_hex_project_to_topo]

ic_hex_get_nearest_existing_point vertex part [""]

Returns the nearest geometry point to a vertex position.

Usage: ic_hex_get_nearest_existing_pointvertex_num

ic_hex_compute_curvature_asf args

Computes the bunching on the blocking edges according to the TGLib size function background grid (must be accessible).

Usage: ic_hex_compute_curvature_asf-asf_mesh_filefname-do_proximity-skip_edges_in_sweep_dir-skip_dimsd1 d2 d3 ...

Argument Descriptions:

Optional arguments:

ic_hex_count_blocks type orfn [0]

Returns the number of blocks.

Usage: ic_hex_count_blocksblock_type<vorfn>

block_type can be free, mapped, or swept.

Set vorfn to 1 to include blocks in part VORFN in the count.

ic_hex_number_all_free_faces

Returns the number of free faces (in 3D) and the number of free blocks (in 2D).

Usage: ic_hex_number_all_free_faces

ic_hex_split_unstruct_block3d_by_edge_loops args

Split a free block by boundary edges.

Usage: ic_hex_split_unstruct_block3d_by_edge_loopsublock_numsheet_num

ic_hex_convert_to_struct_from_nodes args

Convert a free block free face to mapped from four corner vertices.

Usage: ic_hex_convert_to_struct_from_nodes-face free_face -v_end "four_corner_vertices"

ic_hex_get_edge_to_apply n1 n2

When working with superblocks (blocks that have been merged), some edges have hidden vertices that are used internally in scripting. Returns edge vertices required to define the edge in scripting commands given the visible vertices as input.
