### To create a Rigid Wall

 1 From the Menu Bar, select LoadCase > Rigid Wall > Create.
 2 Select the rigid wall type in the window Select RWALL type.
 3 Enter a name in the field beside the Selection type window.

## Rigid wall definition

### Infinite plane

M0M1 defines the plane normal direction:

 • Enter the X, Y and Z coordinates to define M0.
 • Enter the X, Y and Z coordinates to define M1.

### Parallelogram

M0M1 ^ M0M2 defines the plane normal direction:

 • Enter the X, Y and Z coordinates to define M0.
 • Enter the X, Y and Z coordinates to define M1.
 • Enter the X, Y and Z coordinates to define M2.

### Cylinder

M0M1 defines the cylinder axis:

 • Enter the X, Y and Z coordinates to define M0.
 • Enter the X, Y and Z coordinates to define M1.
 • Enter the cylinder diameter.

### Sphere

M0 defines the sphere center:

 • Enter the X, Y and Z coordinates to define M0.
 • Enter the sphere diameter.

 4 Set a distance to automatically define the secondary nodes.

or Select nodes using the different tools from the Selection folder.

 Button Behavior pick nodes in the graphic window, and then press Enter, right-click the mouse button or select Yes or Cancel in the Dialog menu bar. add/remove object by ellipse selection. add nodes by box selection (the default box is rectangular — use the SHIFT key to define a polygon box). remove nodes by box selection (the default box is rectangular — use the SHIFT key to define a polygon box). add all nodes. pick parts in the graphic window, and then press Enter, right-click the mouse button or select Yes or Cancel in the Dialog menu bar. add parts by box selection (the default box is rectangular — use the SHIFT key to define a polygon box). remove parts by box selection (the default box is rectangular — use the SHIFT key to define a polygon box). add the parts selected in the tree. remove the parts selected in the tree.
 5 Click the Properties tab and fill in the appropriate fields:
 6 For the Friction parameters, select from the following:
 • Click Sliding, Tied or Friction and enter the friction coefficient in the corresponding field.
 7 Click Fixed to define a fixed rigid wall.

or

 • Click Moving to define a moving rigid wall. In this case, it is possible to define:
 o the rigid wall mass: fill in the Mass field.
 o the rigid wall initial velocity: fill in the Initial Velocity, Vx, Vy, and Vz fields.
 8 Click See to view the created rigid wall.
 9 Click Save to save the created rigid wall; or

Click Cancel to cancel the rigid wall creation.

 10 Click Close to close the menu.
