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 Modify Region dialog, click the Solution tab.
    Figure 1. The Modify Region dialog (Solution tab).


  5. Under 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 and/or end cap.
    • To define a finite or semi-finite cylinder, select the Start cap and/or End cap check boxes.
    • To define an infinite cylinder, clear the Start cap and End cap check boxes.
  7. Click OK to save the region properties and to close the dialog.
