  • 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:

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

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

  • rbs Geometry – Set geometry option (bottom panel options shown below)
  • rbs Cylind – Set geometry for cylinder
  • Radius: Enter cylinder radius
  • Length: Enter cylinder length
  • rb 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
  • rb 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
  • rb Sphere – Set geometry for sphere
  • Radius: Enter sphere radius

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

  • Label: Set current entity label type

  • cbc Display Node Set – Display Node Set
