MagOasis -- Magsimus Deluxe Tutorials -> Interacting Objects -> Defining the remaining Groups of the Design

We now add the three remaining groups (2, 3 and 4) and their components to the system according to the input specifications given below. Use any of the following two methods to add a new group:

Press the Group button in the Design Manager window (the leftmost button on the top action bar). The group-specification dialog is displayed. Enter the required data inputs and press the OK button.
Right-click the mouse in the in the System Structure list and select the item Add->Group in the displayed popup menu. The group-specification dialog is displayed. Enter the required data inputs and press the OK button.

To add a component to a group, use any of the following methods (in either case first ensure that the appropriate group is selected in System Structure list):

Press the corresponding button ( Element , Array , Probe, Magnetic Shield or Field Array) of the component you want to add (click here for a closeup of the Design Manager). The component-specification dialog is displayed. Enter the required data inputs and press the OK button.
Right-click the mouse in the System Structure list and from the displayed popup menu, select the item Add-> component , where component is any of the appropriate menu items ( Element , Array , Magnetic shield, Probe or Field Array). The component-specification dialog is displayed. Enter the required data inputs and press the OK button.

Each of the new groups that we will create, will contain just one component. To modify the name of a design component first select it by clicking on it once in the System Structure list; then click on it again to edit its text (the name entry for a component in is usually ready for editing after the component is first created).

Group #2

Data inputs in Group specification dialog

Geometry tab

In the frame Group origin relative to previous group (nm) , enter

X = 500

Y = 0

Z = -500

Exit the group specification dialog by pressing the OK button. Change the group name to "Probe holder".

Create a probe component.

Data inputs in Probe specification dialog

Geometry tab

U = 0

V = 0

W = 1000

Data Output tab

Create one data output definition with following specifications:

X- Axis : Iterations (from General data category)

Y - Axis : Y-component electrical current field, HIey (from Electrical data category)

Exit the probe specification dialog by pressing the OK button. In the Design Manager change the probe name to "Field probe."

Remarks . We created a group consisting of a probe object. During a simulation the probe will sense the y -component of the magnetic field generated by currents flowing in the design. This will be plotted as a function of calculation iterations.

Group #3

Data inputs in Group specification dialog

Geometry tab

In the frame Group origin relative to previous group (nm) , enter

X = -500

Y = 0

Z = 500

Exit the group specification dialog by pressing the OK button. Change the group name to "Array group".

Create an array component.

Data inputs in Array specification dialog

Geometry tab

In the frame Size of array cell (nm) , enter:

Length Lu = 500

Width Lv = 100

Thickness Lw = 500

In the frame Spacing between cells (nm) , enter:

Along u = 50

Along v = 50

Along w = 50

In the frame Array matrix dimensions , enter:

Along u = 2

Along v = 1

Along w = 2

Data Output tab

Create one data output definition with following specifications:

X- Axis : System external field amplitude, HextA (from External field data category)

Y - Axis : Magnetization along external field, Mh (from Magnetization data category)

Exit the array specification dialog by pressing the OK button. In the Design Manager change the array name to "Array of 4 magnetic cells."

Remarks. We created a group consisting of a 2 x 1 x 2 array of normal-magnet cells. The cells of the array are non-touching. During a simulation the magnetization curve of the array as a function of applied external field will be plotted.
plotted.

Group #4

Data inputs in Group specification dialog

Geometry tab

In the frame Group origin relative to previous group (nm) , enter

X = 0

Y = 0

Z = 800

Exit the group specification dialog by pressing the OK button. Change the group name to "Biasing field source".

Create an element component.

Data inputs in Element specification dialog

Geometry tab

In the frame Linear dimensions along coordinate axes (nm) , enter:

Length Lu = 1000

Width Lv = 1000

Thickness Lw = 500

Electromagnetic tab

Magnet type : Select Permanent magnet from drop-down list.

In the frame Vector orientation (Deg.) , enter:

Azimuth = 50

Polar = 50

Exit the element specification dialog by pressing the OK button. Change the element name to "Moving permanent magnet" in the Design Manager.

Remarks. We created a group consisting of a permanent magnet, which as the name suggests, will be brought to move during a simulation. We have not defined this motion yet. Motions will be defined in the next section. The magnetization vector of the permanent magnet will be tilted in its local coordinate frame according to the specified vector orientation.

The design and all its components at this stage are displayed in Fig. 8. (You may need to use the zoom-out and zoom-box buttons in the main program tool bar to obtain the view in this figure).

Displaying individual design components

Use the On Display drop-down list of the main program toolbar to display the whole system , a group or a group's individual component. In the figure, the entry "Test design" is currently selected thus, the whole system is displayed on the system-display pane. Selecting a group or component from this list results in only that group or component being shown in the system-display pane. This feature allows the user to interact with individual groups or components separately from the rest of the system.
