HFSS15: Drawing a Cylinder
录入：edatop.com 点击：
Draw a cylinder by selecting a center point, radius, and height. Cylinders are drawn as true surfaces in the modeler.
1. Click Draw>Cylinder
.
2. Select the center point of the cylinder’s base circle in one of the following ways:
• Click the point.
• Type the point’s coordinates in the text boxes in the status bar.
3. Specify the radius by selecting a point on the base circle’s circumference in one of the following ways:
• Click the point.
• Type the coordinates of the point relative to the center point in the dX, dY, and dZ boxes, where d is the distance from the previously selected point.
4. Specify the cylinder’s height by selecting a point on the axis perpendicular to the base circle’s plane. Select the point by clicking the point or typing the coordinates in the dX, dY, and dZ boxes.
Note | If you create a cylinder with a height of zero, HFSS draws a circular sheet object. |
If the Modeler option for editing properties of new primitives is checked, the Properties dialog box appears, enabling you to modify the object’s properties.
5. Click OK.
Note | The 3D Geometry Modeler permits drawing of true-curved objects. However, the solution will be obtained with a tetrahedral mesh which conforms to the true surface only within the limits identified by certain mesh settings. The modeler has default settings for this conformance which is a reasonable trade-off between solution speed and solution quality for most objects, but may not be ideal for all such objects. High-aspect ratio curves structures, such as helices with narrow and curved cross-sections, may benefit from user control of the faceting values. For details about these commands see: Technical Notes, "Surface Approximations" and related sections, Rectilinear Elements and Curvilinear Elements, "Modifying Surface Approximations," and "Guidelines for Modifying Surface Approximations" |
