Geometry I
Start by drawing the geometry; one sphere (the orange) and two cylinders (the metal nails, zinc, and copper). Both shapes are available in the Geometry toolbar.
Sphere I
1
In the Geometry toolbar, click Sphere .
2
In the Settings window for Sphere, locate the Size section and type 5e-2 in the Radius text field.
Zinc nail
1
In the Geometry toolbar, select Cylinder .
2
In the Settings window for Cylinder, type Zinc nail in the Label text field.
3
Locate the Size and Shape section.
- In the Radius text field, type 2e-3.
- In the Height text field, type 5e-2.
4
Locate the Position section.
- In the x text field, type -2e-2.
- In the z text field, type 2e-2.
5
Locate the Selections of Resulting Entities section. Select the Resulting objects selection checkbox and choose All levels in the Show in physics list. By enabling this setting you can easily select all boundaries of the nail later on when setting up the physics.
Duplicate the cylinder and change the x position to draw the second nail.
Copper nail
1
Right-click Component 1 > Geometry 1 > Zinc nail and click Duplicate .
2
In the Settings window for Cylinder, type Copper nail in the Label text field.
3
In the Position section enter 2e-2 in the x text field.
