• Figure 1 – Mesh Interface

Purpose:

This interface, often used for generating solid meshes for ALE simulations, can be used to generate solid and shell meshes based on the following geometric forms:

• Cube
• Cylinder
• Sphere
• Surface defined by 4 nodes

Controls:

• Entity: Create mesh for the entity
• (Box_Solid, Box_Shell, 4N-Shell, Sphere_Solid, Sphere_Shell, Cylinder_Solid, Cylinder_Shell)

• Box_Solid, Box_Shell

Call Position Dialog to get minimum point

Call Position Dialog to get maximum point

• X: Enter x-coordinates of minimum and maximum point
• Y: Enter y-coordinates of minimum and maximum point
• Z: Enter z-coordinates of minimum and maximum point

• Nx: Enter number of elements along x
• Ny: Enter number of elements along y
• Nz: Enter number of elements along z
• 4N-Shell
• P1 – Pick node ID for point 1 or enter XYZ coordinates
• P2 – Pick node ID for point 2 or enter XYZ coordinates
• P3 – Pick node ID for point 3 or enter XYZ coordinates
• P4 – Pick node ID for point 4 or enter XYZ coordinates

Call Position Dialog to get point 1-4

• NxNo.:Enter number of elements along x
• NyNo.:Enter number of elements along y
• Sphere_Solid, Sphere_Shell
• Density: Enter density of sphere

Call Position Dialog to get sphere center

• X: Enter x-coordinate of sphere center
• Y: Enter y-coordinate of sphere center
• Z: Enter z-coordinate of sphere center

Call Direction Dialog to get direction 1

Set direction x for 1/-1 (toggles)

Set direction y for 1/-1 (toggles)

Set direction z for 1/-1 (toggles)

Call Direction Dialog to get direction 2

Set direction x for 1/-1 (toggles)

Set direction y for 1/-1 (toggles)

Set direction z for 1/-1 (toggles)

• Cylinder_Solid, Cylinder_Shell
• Length: Enter cylinder length
• Num Ele: Enter number of elements in circumferential direction
• Num Leng: Enter number of elements along the length of the cylinder

Call Position Dialog to get position

• x: Enter coordinate x value
• y: Enter coordinate y value
• z: Enter coordinate z value

Call Direction Dialog to get direction

Set direction x for 1/-1 (toggles)

Set direction y for 1/-1 (toggles)

Set direction z for 1/-1 (toggles)

• Target Name: Enter target part name
• Target PID: Enter target part ID
• Start EID: Enter starting element ID
• Start NID: Enter starting node ID
