Sample Problem: Cylindrical Halfraum at OMEGA

Setting Up the Grid: Sample Package

The Sample Package represents an experimental package placed at the end of the halfraum which is exposed to its radiation field.

Here, we place a package in the form of a disk just outside the bottom of the halfraum.

• Select Target | Add Object.
• Select "Disk" for the target component type.
• Set the object name to "Sample_package".
• In the Position tab of the Object Parameters Dialog:
• For the Reference Coordinate System, select "Halfraum".
• Set the object position: r = (0, 0, -0.06); this is at the z-position of the bottom disk of the halfraum.
• Use the default orientation angles (all angles zero).
• In the Size/Gridding tab of the Object Parameters Dialog:
  • Set the outer radius to 0.04 cm.
  • Set the inner radius to 0.0 cm.
  • Set surface normals up (toward the center of the halfraum).
  • Use 7 grid points along the radial direction.
  • Set the number of azimuthal grid points to 18 (20 degrees per node).
• Select "OK".

Since it could be somewhat difficult to see much contrast between the bottom of the halfraum and the package, we give the package a different color. Press the "Color" button to set the color.
