Description

Creates a 2D seat belt mesh only.

Inputs

entity_type
The entity type around which the seat belt should be wrapped.
  • Components.
  • Elements.
  • Ellipsoids.
mark_id
The ID of the mark containing the wrapped seat belt entities. Valid values are 1 and 2.
node_list_id
The ID of the list of nodes for the seat belt orientation, including from node, middle nodes and to node. Valid values are 1 and 2.
gap
The offset for the seat belt from the surface of the entities.
width
The total width of the 2D element section of the belt.
from_end_length
The length on the "from" end where the seat belt is one-dimensional.
to_end_length
The length on the "to" end where the seat belt is one-dimensional.
start_vector
The ID of the vector created by *createvector that defines the starting edge of the seat belt. Valid values are:
  • 0 - Ignored.
  • 1
  • 2
end_vector
The ID of the vector created by *createvector that defines the ending edge of the seat belt. Valid values are:
  • 0 - Ignored.
  • 1
  • 2
use_default_ends
0 - Use user-defined start and end vectors.
- Use default end vectors (recommended).
use_rigid_link
0 - Use tria element transitions to 1D lines at each end of the seat belt.
1 - Use rigid link transitions to 1D lines at each end of the seat belt.
mesh_type
0 - Tria.
1 - Quad.
mesh_size
The element size used for the 2D mesh.
1d_comp_name
The name of the component into which the 1D elements will be organized.
2d_comp_name
The name of the component into which the 2D elements will be organized.

Examples

To create a 2D seat belt mesh only, around the selected components, using nodes 17373, 13032, 20870 and 34327, a gap of 5, a width of 50, end lengths of 25, using default vectors, using rigid links at the ends, using quad mesh type, and an element size of 8:
*createmark components 1 "Fabric seat cushion" "UPPER TORSO" "LOWER TORSO" "PELVIS" "LINK"
*createlist nodes 1 17373 13032 20870 34327
*createseatbeltmesh components 1 1 5 50 25 25 0 0 1 1 1 8 "SeatBelt1DElems" "SeatBelt2DElems"
The same example, but using user-defined vectors:
*createmark components 1 "Fabric seat cushion" "UPPER TORSO" "LOWER TORSO" "PELVIS" "LINK"
*createlist nodes 1 17373 13032 20870 34327
*createvector 1 -10.9962736 -19.0656596 -11.856753
*createvector 2 -23.9343219 -5.5677975 -4.59868088
*createseatbeltmesh components 1 1 5 50 25 25 1 2 1 1 1 8 "SeatBelt1DElems" "SeatBelt2DElems"

Errors

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:
if { [ catch {command_name...} ] } {
   # Handle error
}
