Use the Rigid Walls panel to create and update rigid walls.
Location: Analysis page or Analysis page > Safety module
Rigid walls are used to define a contact or sliding rigid wall in an analysis code. In all solver
interfaces except for LS-DYNA, rigid walls are created as
group entities with configuration 5. In the LS-DYNA solver
interface, rigid walls are created as rigid wall entities.
You can define the nodes included in a rigid wall using one of the four methods.
- nodes
- Create a secondary node for each node included in the rigid wall.
- components
- Provide a list of components. In this case, the analysis code is
provided with a list of component IDs.
- sets
- Select one or more previously defined entity sets. In this case, the
analysis code is provided with a list of the entity set IDs.
- all
- Include all the nodes in the model. If you select all, the keyword ALL
is used.
You can also select one or more previously defined entity sets. In this case,
the analysis code is provided with a list of the entity set IDs.
The Rigid Walls panel displays fields for dictionaries or card images depending on the type of
solver template that is referenced. If a card image template
is loaded, or no template is loaded, the panel displays card image related fields. If a dictionary template is loaded,
the panel displays dictionary related fields. Card image and dictionary entry fields
are used in the same way except that when a card image
solver is being used and edit is selected, the card image is
displayed in a new area of the screen. For dictionary solvers, the data is shown in
the existing menu area.
This function requires a template file.

new rigid wall. |
Update Subpanel
Option |
Action |
name = |
Click to select an
existing rigid wall. |
type = |
Select a rigid wall
type. |
rgdwall color |
Select a color for the entity. |
Geom Subpanel
Option |
Action |
name = |
Click to select an
existing rigid wall. |
shape: |
Select the desired
shape. |
base node |
Select the base node
for the rigid wall. Click edit to
directly change the node's coordinates. |
normal vector: |
Choose a method for
defining the rigid wall's normal vector.
- vectors
- Use a standard plane and vector selector to define
the vector via nodes or axes.
- components
- Manually specify the X, Y, Z components of the
vector.
- systemid
- Define the vector by means of selecting a local
system.
|
shape: |
Define the geometric information.
- finite plane
- Define a finite plane using the selector to choose
either the corner or dist/axis creation method.
- Use the corner method by selecting two
nodes.
- Use the dist/axis method using the vector
selector to specify the local x axis of the plane,
then specify the lengths of the local x and y
directions of the plane.
- finite prism
- Define a finite prism using the selector to choose
either the corner or dist/axis creation method.
- Use the corner method by selecting two
nodes.
- Use the dist/axis method using the vector
selector to specify the local x axis of the prism,
then enter the lengths of the local x, y, and z
directions of the prism.
- cylinder
- Define a cylinder using the selector to choose
either the node or radius creation method.
- Use the node method to select a node that
describes the radius of the cylinder.
- Use the radius method to enter the desired
radius of the cylinder.
- Specify the desired length of the cylinder. If
the length of a cylinder is zero, it is assumed to
be infinite.
- sphere
- Define a sphere using the selector to choose either
the node or radius creation method.
- Use the node method to select a node that
describes the radius of the sphere.
- Use the radius method to enter the desired
radius of the sphere.
- parallel
- Specify two nodes as corner nodes of the parallel
shape.
|
shape:
infinite/finite |
If plane or prism is
selected for the shape, select infinite or finite. To describe
an infinite plane or prism, no additional input is needed,
additional details for a finite plane are described for
shape. |

secondary: |
Select the secondary
entities.
- nodes
- Create a secondary node for each node included in the
rigid wall.
- components
- Provide a list of components. In this case, the
analysis code is provided with a list of component
IDs.
- sets
- Select one or more previously defined entity sets.
In this case, the analysis code is provided with a
list of the entity set IDs.
- all
- Include all the nodes in the model. If you select
all, the keyword ALL is used.

Motion Subpanel
Option |
Action |
name = |
Specify a name for the
rigid wall to which you want to add a motion
description. |
motion switch |
Choose between vectors
and components to define the direction and magnitude of the
motion.
- vectors
- Specify a value in the magnitude= field, then use
the standard plane and vector selector to define the
direction.
- components
- Specify the x,y,z values of the components.
