target location.

Type
HyperMesh Tcl Modify Command
Description
Moves a selection of elements and pastes them onto the displayed shell elements at the
target location. The neighborhood of the pasted region will be remeshed. If the selected
entities are connected to another mesh at the source, they are detached from them. Any holes
left behind are patched and remeshed. Doesn’t allow moving elements associated to
geometry.
Inputs
- entity_type
- The type of entity to copy. Valid values are components and elements. The selection
may consist of shell or solid elements. Any 1D elements attached to shell elements are
automatically included.
- mark_id
- The ID of the mark of entities. Valid values are 1 and 2.
- string_array
- The ID of the string array that contains the additional input parameters. The string
array is created using the *createstringarray command. This should
always be set to 1.
- All parameters are case insensitive, order insensitive and optional. If not supplied,
the default values will be used. Valid parameters and their syntax are:
- NumLayers : <value>
- The number of layers to remesh (default 2).
- MappingMethod : <value>
- The method in which the transformed feature's stitch boundary is mapped on to
the target mesh:
- auto – (default) Decides the best method among extend, morph and none based on
the way the selected feature is connected to the the target mesh.
- extend – The stitch boundary is extended till it meets the target mesh, or if it
already crosses the target mesh, the extended part of the mesh is trimmed out.
This is ideal for features that intersects sharply with the target mesh.
- morph – The feature is morphed such that the stitch boundary conforms to the
target mesh. This is ideal for features that meet the target mesh
tangentially.
- none - The transformed feature is kept as it is.
- Rebuild : <value>
- 0 - Remesh using size and bias.
- 1 - Remesh using rebuild (default).
- StitchBoundary : <node_id1> <node_id2> … <node_idN-1>
<node_idN>
- The mesh edges that needs to be extended or trimmed from or morphed to the
target mesh, and subsequently be stitched with the target mesh. In most cases the
command can deduce which mesh edges are to be extended or morphed. But when it
comes to features which already cross the target mesh this needs to supplied so
that the command knows where to trim from.
- This is a list of node IDs of the involved edges. It expects two node IDs per
mesh edge. If there are N edges to be supplied, there should be 2N node IDs in
this list. For example:
- StitchBoundary: n1 n2 n2 n3 n3 n4.
- TransformByMatrix : <tr11> <tr12> <tr13> <tr14> <tr21> <tr22>
<tr23> <tr24> <tr31> <tr32> <tr33> <tr34> <tr41> <tr42>
<tr43> <tr44>
- The transformation specified as a 4x4 matrix.
- TransformByNodes : <sn1> <sn2> <sn3> <tn1> <tn2> <tn3>
- The transformation specified between two systems defined at source and target
locations. The system at source is defined by three nodes sn1, sn2 and s3. The
origin is defined by the node sn1. The x-axis is defined by the vector from sn1 to
sn2. The x-y plane is defined as the plane containing all three nodes sn1, sn2 and
sn3. Similarly, the system at target is defined by three nodes tn1, tn2 and tn3.
- number_of_strings
- Integer indicating the size (number of strings) in the string array created using
*createstringarray.
Example
To move elements 5100-5200 along the -y direction with a distance of 1, and remeshing 2
layers with the rebuild algorithm:
*createstringarray 5 "TransformByMatrix : 0 -1 0 0 1 0 0 0 0 0 1 0 0 0 0 1 " "MappingMethod : morph" "Rebuild : 1" "NumLayers : 2"
*createmark elements 1 5100-5200
*copy_feature elements 1 1 5
Errors
Incorrect usage results in a
Tcl error. To detect
errors, you can use the
catch
command:
if { [ catch {command_name...} ] } {
# Handle error
}
