HFSS15: Geometry Command
录入：edatop.com 点击：
The Fields Calculator Geometry command opens a dialog that lets you select a geometry to load into the top register of the calculator. Do this to:
• Find the value of derived field quantities on any point, line, surface, or volume.
• Plot quantities directly from the calculator.
• Display a previously defined isosurface, maximum or minimum field point using the Draw command.
The following types of geometries are available:
Point - See drawing a point object. Points you draw are listed in the history tree, and in the Calculator Geometry dialog when you select Point. |
Line- See drawing a line object. Lines you draw are listed in the history tree, and in the Calculator Geometry dialog when you select Line. To set the number of points on a line, see Geom Settings . |
Surface - Sheet objects and face lists which you can make, (for example of radiation boundaries) are listed under surface in the history tree and in the Calculator Geometry dialog when you select Surface. Due to the ambiguity of the normal vector of a sheet, the result may require a multiplication by ( 1 ) or ( -1 ). |
Volume - 3D objects, Regions, and object lists of 3D objects including AllObjects are available in the Calculator Geometry dialog when you select Volume. |
Coord - Coordinate systems are available in the Calculator Geometry dialog when you select Coord. |
To load a geometry into the calculator:
1. In the Fields Calculator, click Geometry.
The Geometry dialog box appears.
2. Select a geometry type.
A list of all applicable geometries appears.
3. Click the geometry.
4. Click OK to load the geometry.
Note | Consider a box (Box2) that is completely enclosed in a bigger box (Box1), so that no faces of Box2 are touching any faces of Box1. Box2 is actually implicitly subtracted from Box1 as is done in our solvers. So Box1 is used as if Box2 were already subtracted from Box1. Volume(Box1) is Box1 excluding Box2, and Surface(Box1) contains faces from both Box1 and Box2. |
