System Collectors and Systems
System Collectors
System collectors collect and organize systems.
LS-DYNA Cards
| Card | Description |
|---|---|
| *DEFINE_TRANSFORMATION | Define a transformation for the INCLUDE_TRANSFORM keyword
option. Note: Transformations can be created using the Transformation
Manager.
|
| *INCLUDE_PATH | Defines path for the include file location. Note: Card Edit is not available.
Keyword details can be accessed from the Include file options in the Include
browser.
|
| *INCLUDE_STAMPED_PART | Attaches a file that has stamping results for a part in the model as an
include file. Note: Card Edit is not available. Keyword details can be accessed
from the Include file options in the Include browser.
|
| *INCLUDE_STAMPED_PART_SET | Attaches a file that has stamping results for a collection of parts (set) in
the model as an include file. Note: Card Edit is not available. Keyword details can
be accessed from the Include file options in the Include browser.
|
| *INCLUDE_TRANSFORM | Include file that supports offset on its content IDs and transforms on its
contents. Note: HyperMesh support offset on the
entity ID's. During import, offsets are applied on to the ID's of the
corresponding include_transform file contents. During export, offset is
subtracted from the ID's. The current release only supports Input and output
therefore the offsets cannot be changed.
|
| *NODE_TRANSFORM | Transformation defined on node set. Note: Transformations can be created using
the Transformation Manager.

Systems
System entities, commonly called coordinate systems, can be defined as rectangular, cylindrical, or spherical coordinate systems.
Every system must be organized into one system collector, and therefore are mutually exclusive to a system collector.
- Reference System
- Defines the geometric positions of entities.
- Displacement System
- Defines the nodal degree of freedom coordinate system assigned to a node.
Abaqus Cards
| Card | Description |
|---|---|
| *ORIENTATION | Define a local axis system for material or element property definition, for
kinematic coupling constraints, for free directions for inertia relief loads, or
for connectors. Note: The *ORIENTATION card needs a name in Abaqus. Since systems do not have a name, a name needs to
be entered in the system card image. The restriction of one system per system
collector has been removed with version 10.0 – SA1-130.
DEFINITION = NODES option with only two nodes is converted to DEFINITION=COORDINATES upon import from an input file. *ORIENTATION with SYSTEM = Z RECTANGULAR is converted to RECTANGULAR upon import from an input file. |
| *SYSTEM | Specify a local coordinate system in which to define nodes. Note: Whenever a
system is assigned to nodes with the set reference option from the Systems panel
activated, a *SYSTEM card is exported before the node block of its
assignment.
|
| *TRANSFORM | Specify a local coordinate system at nodes. Note: If assigned to individual
nodes, on export each *TRANSFORM card creates references to an automatically
generated *NSET card. This *NSET card is followed by the list of the nodes that
are assigned to the coordinate system with the set displacement
option.
Systems can be assigned to node sets with the same assignment procedure. |

PAM-CRASH Cards
| Card | Description |
|---|---|
| FRAME / | Local frame definition - system collectors Note: If there is a $HMMOVE
directive found for a system and that system collector exists in the model, the
system is placed in that collector. Otherwise, a separate system collector is
made for the frame. If a base node is not given, the system is created at the
global origin 0, 0, 0. In case of frame definition with nodes, the system is
created at the first node.
