Syntax

*imprint_geom entity_type_target mark_id_target entity_type_source mark_id_source ?options?

Type

HyperMesh Tcl Modify Command

Description

Imprints, connects source points, nodes, lines and surfaces onto target FE surfaces. This command does not support surfaces that are not FE. Points and lines could be any type. In the case that input is an FE entity, the command optionally remeshes the input entities.

Inputs

entity_type_target

The type of entity to use as the target (destination) for the imprint. Valid values are surfaces.

mark_id_target

The ID of the mark containing the target (destination) entities to imprint. Valid values are 1 and 2.

entity_type_source

The type of entity to use as the source for the imprint. Valid values are points, nodes, lines, surfaces.

mark_id_source

The ID of the mark containing the source entities to imprint. Valid values are 1 and 2.

options

List of input options, passed as a space separated string enclosed in quotes. Valid options are:

angle <value>: The angle used to define feature edges on the mesh. If not defined, 25.0 is used.
max_distance <value>: The command will exit with an error if the distance between source and destination exceeds this value. If not specified, this is ignored.
mesh_size <value>: Automatically detected from input mesh if not provided.
mesh_type <value>: Automatically detected from input mesh if not provided.; 0 - tria; 1 - quad; 2 - mixed; 3 - R-tria; 4 - quad only
projection <value>: 0 - Normal to destination (default if not provided).; 1 - Along tangent.; 2 – Along vector direction, if defined 3 doubles should be defined in projection_vector.
projection_vector <x y z>: 3 doubles defining the vector direction. Should be defined if projection is set to 2.
remain <value>: 1 - Source remains, source node coordinates are kept (default if not provided).; 2 - Destination remains, node coordinates projected to destination are used.; 3 - Both remain, source entities are projected and a copy is imprinted to destination.; 4 - Create patch between source entities and the imprinted copy to destination.
remesh_mode <value>: -1 - No remesh. Element connectivity is maintained by recovery of the imprinting element edges.; 0 - Do not remesh destination. Destination mesh is stitched to maintain element connectivity.; 1 - Remesh all input destination elements.; 2 - Remesh destination elements defined by remesh_layers.
remesh_layers <value>: Must be defined if remesh_mode is 2.; 0 - Remesh only the elements attached to the border of the imprinted element image.; > 0 - Remesh additional layers in addition to the elements attached to the imprinted element image.; .
to_dest_component <value>: -1 - Create elements in source component.; 0 - Create elements in current component (default if not provided).; 1 - Create elements in destination component.
do_not_remesh_rebuild_extn <value>: 0 - Remesh / rebuild extension (default is not provided).; 1 - Do not remesh / rebuild extension.
do_not_add_fixed_points_edges <value>: 0 - Add fixed points / edges on nodes imprint (default if not provided).; 1 - Do not add fixed points / edges on nodes imprint.
anchor_nodes_mark <value>: The ID of the mark containing the anchor nodes used for imprint. If not provided no anchor nodes are used for imprint.

Examples

To imprint surfaces 20 and 21 onto surface 45, using a normal projection, a feature angle of 30, keeping the source, and remeshing the destination using 2 layers:

*createmark surfs 2 20 21
*createmark surfs 1 45 
*imprint_geom surfs 2 surfs 1 "remain 1 remesh_mode 2 remesh_layers 2 angle 30.0"

Errors

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:

if { [ catch {command_name...} ] } {
   # Handle error
}
