Sample Problem: Z-Pinch Hohlraum

Setting Up the Grid: Top and Bottom Plates

To set up the top and bottom plates of the hohlraum:

• Select Target | Add Object (or push the Add Object tool button).
• Select "Disk" for the target component type.
• Set the object name to "Top Plate".
• In the Position tab of the Object Parameters Dialog:
• For the Reference Coordinate System, use "Target Chamber".
• Set the object position to: r = (0, 0, 1.0).
• Use the default orientation angles (all angles zero).
• In the Size/Gridding tab of the Object Parameters Dialog:
  • Set the outer radius to 2.5 cm.
  • Set the inner radius to 0.0 cm.
  • Set surface normals down.
  • Use 10 grid points in the radial direction.
  • Set the number of azimuthal grid points to 18 (20 degrees per node).
• Select "OK".
• The plates are added in the graphics window.

Repeat the above steps for the "Bottom Plate", with the following differences:

• In the Position tab of the Object Parameters Dialog:
  • Set the object position to: r = (0, 0, -1.0).
• In the Size/Gridding tab of the Object Parameters Dialog:
  • Set surface normals up.
  • Set the outer radius to 2.0 cm (this leaves a 0.5 cm gap).
