• Figure 1 – Wall Interface

## Purpose:

This interface is used for showing, creating, modifying, and deleting *RIGIDWALL cards in LS-DYNA. The main advantage of this interface is the ability to graphically view the various rigidwall definitions with the flexibility of positioning them using translate, rotate, and reflect functions.

## Controls:

• Show – Show existing *RIGIDWALL entities
• Modify – Modify existing *RIGIDWALL entities
• Create – Create new *RIGIDWALLN entities
• Delete – Delete existing *RIGIDWALL entities

For Show, Modify, and Delete, the Entity Operation Interface is displayed in the secondary controls area.

• Geometry – Set geometry option (bottom panel options shown below)
• Cylind – Set geometry for cylinder
• Length: Enter cylinder length
• Flat – Set geometry for flat
• Flat Length: Enter flat length
• Flat Width: Enter flat width

• Node X: Pick or ender ID of node at y-coordinate of head of edge vector l
• Node Y: Pick or ender ID of node at x-coordinate of head of edge vector l
• Node Z: Pick or ender ID of node at z-coordinate of head of edge vector l
• Prism – Set geometry for prism
• Pri_L: Enter prism length
• Pri_W: Enter prism width
• Pri_H: Enter prism height

• Node X: Pick or ender ID of node at y-coordinate of head of edge vector l
• Node Y: Pick or ender ID of node at x-coordinate of head of edge vector l
• Node Z: Pick or ender ID of node at z-coordinate of head of edge vector l
• Sphere – Set geometry for sphere

• Planar – Set planar option (bottom panel options shown below)
• Finite – Set planar for finite
• Forces – Set planar for forces
• Moving – Set planar for moving
• Mass: Total mass of stonewall
• VO: Initial velocity of stonewall in direction of defining vector, n
• Ortho – Set planar for ortho

• Label: Set current entity label type

• Display Node Set – Display Node Set
