Rigid Walls Panel

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 slave 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.

Create Subpanel

Option	Action
name =	Specify a name for the rigid wall that you wish to create.
type =	Select a rigid wall type.
creation method	Select a card image. card image Select a card image. no card image Do not use a card image. same as Select a collector that already uses the desired card image.
rgdwall color	Select a color for the entity.
size =	Specify a size for the 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. madymo plane or ellipse Define a coupled MADYMO plane or ellipse, choose either to enter the ID of the plane or ellipse in the MADYMO input deck. 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.

Motion Subpanel

Option	Action
name =	Specify a name for the rigid wall to which you want to add a motion description.
