Creating a UTD Cylinder

Solve a cylinder with the uniform theory of diffraction (UTD). The cylinder can either be a finite, semi-infinite or infinite, depending on the termination type of the start cap and end cap.

  1. Create a cylinder.
  2. Select the cylinder in the 3D view or in the details tree.
  3. In the details tree, from the right-click context menu, select Properties.
  4. On the Region properties dialog, click the Solution tab.

    Figure 1. The Region properties dialog (Solution tab).
  5. Under Solve with special solution method, from the drop-down list, select Uniform theory of diffraction (UTD) cylinder.
  6. Under Termination type, specify if the UTD cylinder is infinite or finite sized at the start cap.
    • To define a finite cylinder, select the Start cap check box.
    • To define an infinite cylinder, clear the Start cap check box.
  7. Repeat Step 6 for the end cap.
  8. Click OK to save the region properties and to close the dialog.
