Getting Started: A 2D Magnetostatic Problem Assign Materials to Objects The next step in setting up the solenoid model is to assign materials to the objects in the model. Materials are assigned to objects via the Material Manager, which is accessed through the Setup Materials command. You will do the following: • Assign copper to the coil. • Define the material cold rolled steel (a nonlinear magnetic material) and assign it to the bonnet and yoke. • Define the material Neo35 (a permanent magnet) and assign it to the core. • Define the material SS430 (a nonlinear magnetic material) and assign it to the plugnut. • Accept the default material that is assigned to the background object, which is vacuum. Access Material Manager To access the Material Manager, click Setup Materials. The Material Manager appears. 4-2 Setting Up the Model
Assign Copper to the Coil Getting Started: A 2D Magnetostatic Problem The Material Manager should still be on the screen. In the actual solenoid, the coil is made of � copper. To assign the material copper to the coil: 1. Select the object that is to be assigned a material — the coil — in one of two ways: • Click the name coil in the Object list. • Click the object coil in the geometry. Both the object and its name are highlighted. Note To deselect an object, simply click on it. To select multiple objects from the Object list, click Multiple Select, and hold down the Ctrl key and click each object. As an alternative to selecting and deselecting objects with the mouse, use the Select commands (which appear beneath the Multiple Select button in the Material Manager). They are described in Maxwell 2D’s online help. 2. Select copper from the Material database listing. If it does not appear in the box, use the scroll bars to pan through the list as described in Chapter 3, “Creating the Model.” 3. Click the Assign button, which is located above the Material list. Copper now appears next to coil in the Objects list. Assign Cold Rolled Steel to the Bonnet and Yoke The bonnet and yoke of the solenoid are made of cold rolled steel. Since this material is not in the database, you must create a new material, ColdRolledSteel. This material is nonlinear — that is, its relative permeability is not constant and must be defined using a B vs. H curve. Therefore, when you enter the material attributes for cold rolled steel, you will also define a B-H curve. Select Objects and Create the Material To select the objects and create the new material: 1. If it is not already selected, select the Multiple Select radio button from the top of the menu. 2. Select bonnet and yoke. 3. Click Material>Add from the Material pull-down menu. 4. Under Material Properties, change the name of the new material from Material80 to Cold- RolledSteel. 5. Select B-H Nonlinear Material. The Rel. Permeability (Mu) field changes to a button labeled B H Curve. Setting Up the Model 4-3
