UZ Card
The UZ card is used to create a cylinder that will be solved with the 回折均一理論 (UTD).
On the Construct tab, in the Surfaces group,
click the Cylinder icon. From the ドロップダウンリスト, click the
Unmeshed cylinder (UZ) icon.

Figure 1. The UZ - Specify a UTD cylinder dialog.
Parameters:
- S1
- The start point of the cylinder axis (previously defined with a DP card).
- S2
- The end point of the cylinder axis (previously defined with a DP card).
- S3
- A point on the radius of the cylinder. The angle S2–S1–S3 must be 90°.
- S1 side end-cap
- Select a flat end cap or a semi-infinite end on the side of S1.
- S2 side end-cap
- Select a flat end cap or a semi-infinite end on the side of S2.
Example of UZ Card Usage
The UZ card is used to create a UTD cylinder. Note the absence of discretisation.Figure 2. Example of cylinder created with the UZ card.
