Magneto-Structural Coupling--Step-by-Step Description: Step 3
Creating geometry elements
First, we should make a decision concerning dimensions of the problem's region. Since the problem has vertical axis of symmetry, it is convenient to set zero of x-axis at the axis of symmetry.
The first step with the new model in Model Editor is to adjust window dimensions fitting the problem's region. Since none of the physical quantities varies along z-axis, we'll model a thin slice of the solenoid. We'll choose the axial length of this slice to be 0.2 cm, from –0.1 to 0.1 along z-axis. The whole model fits in the square (–1 ≤ z ≤ 1, 0 ≤ r ≤ 2). To make this rectangle occupying most of the window:
-
On the toolbar, click Zoom In.
-
Move mouse pointer to (–1, 0), checking the coordinates in lower right corner of the QuickField application window. You need not position mouse exactly at this point but somewhere to the bottom left not far the point.
-
Click the left mouse button and drag to (1, 2).
-
The window reflects your zoom operation. Click Zoom In once again co close zooming mode.
To simplify object creation, we'll use Snap to Grid feature.
To set up the 0.1 cm grid:
-
On Edit or context menu, click Grid Settings, a dialog box appears.
-
In the Horizontal box, type 0.1. Since Anisotropic box is unchecked, the same value appears in Vertical box.
-
Grid origin at (0, 0) is okay, so we need not change anything else. Click OK to close the dialog.
