'''Pre-requisites'''

'''spoken-tutorial.org'''

| | To practice this tutorial, you should have '''OMEdit''' installed on your system.

You should also know how to work on the '''OMEdit''' window.

If not, please go through the previous '''OpenModelica''' tutorials on this website.

|-
| | /* Switch to OMEdit */
| | Let us switch to the '''OMEdit''' window.

|-
| | Point to '''Dash Home''' >> Click on '''Dash Home'''.
| | To open '''OMEdit''' window, click on '''Dash Home'''.

|-
| | Type '''OMEdit''' in the search bar >> click on '''OMEdit'''
| | In the search bar, type '''OMEdit'''.

Click on the '''OMEdit''' icon that is displayed.

|-
| | Switch to '''Libraries Browser'''

| | On the left side of '''OMEdit''' window, we see the '''Libraries Browser'''.

Here we can see a list of libraries.

|-
| |

| | Now I will demonstrate an example from the '''Electrical''' library.

|-
| | /* Expand '''Electrical''' Library */

Expand '''Electrical''' library >> Expand '''Analog''' library

| | Expand the '''Electrical''' library.

Click on the arrow head to the left of '''Electrical''' library.

Under '''Electrical''', we find '''Analog''' library.

Let's expand the '''Analog''' library.

|-
|| /* Expand '''Example''' Library */

| | Once again, we see many different libraries displayed.

Now, let’s expand the '''Example''' library.

Here we can see different examples of '''Analog'''.

|-
| | /* Opening '''Rectifier''' Class in '''Example''' Library */

Right click '''Rectifier''' >> '''Open Class'''

| | Next, we will open the class named '''Rectifier'''.

Right-click on '''Rectifier''' and select '''Open Class'''.

We can also double-click on the class name to open the class.

|-
| | Switch to '''Modeling Perspective''' window

Switch to '''Diagram View'''.

| | Now we are in the '''Modeling Perspective''' window.

By default, the class opens in '''Diagram View'''.

I have already demonstrated how to switch between different views earlier in this series.

|-
| | /* Switch to '''Text View''' */

Click on '''Text View''' button next to '''Diagram View'''.

| | Now let's switch to the '''Text View''' by clicking on the '''Text View''' icon.

Here we can see the '''Modelica''' code pertaining to the '''Rectifier''' class.

|-
| | /* Checking a Class */

| | Before simulating a model, we need to check for the correctness of the model.

|-
| | Click green button with white coloured double tick
| | To do this, first locate '''Check All Models''' button on the toolbar.

This button has white coloured double ticks on it.

Click on it.

|-
| | Getting error messages in '''Messages Browser'''.

Cursor on the '''Messages Browser'''.

|| Immediately, the '''Messages Browser''' opens at the bottom of the window.

This will show all the messages pertaining to the '''Modelica''' class.

|-

|| On simulating, a new window opens.

|-
| | Hover the mouse on '''simulation output''' window.
| | It shows the compilation process of the class.

|-
|| Point to the success message.
| | Once the compilation is successful, the output window displays the message:

'''Simulation process finished successfully'''.

Close this window.

|-
| | /* Switching to '''Plotting Perspective''' */
|| By default, the '''Plotting Perspective''' should now open in the '''OMEdit''' window.

If it does not open, click the '''Plotting''' button at the bottom right.

|-
| |

| | Here we can see the simulation results of the '''Modelica''' class.

|-
| | Switch to '''Variables Browser'''.
| | At the right of the '''Plotting Perspective''', look at the '''Variable Browser''' window.

|-
| | Point to '''Variables Browser'''.
| | Under '''Variables Browser''':

we will learn to change input variable values of a '''Modelica''' class.

|-
| | Point to '''IDC''' and '''Losses'''.
|| By default, '''IDC = 500''', '''Losses = 2890.26'''

Change the value of '''IDC''' and see how the values of '''Losses''' change.

|-
| | Change '''IDC''' value to '''250'''.
| | Let us change the value of '''IDC''' from '''500''' to '''250'''.

Type '''250''' and press Enter.

|-
| | Click '''Re-simulate''' button.
| | Go to the top right corner of the window.

Click '''Re-simulate''' button.

|-
| | Point to the message >> minimize the window
| | The success message window will open.

Close this window.

|-
| | Point to the changes.
|| Once the simulation is completed, note the changes.

'''Losses = 1756.77'''

|-
| | Cursor on the plot window.
|| Now let me demonstrate how to generate a plot.

We will generate a plot between '''Losses''' and '''Time'''.

|-
| | Click on check box against '''Losses''' variable.
|| Click on the check box against the '''Losses''' variable.

|-
|| Point to the plot, '''Losses on Y-axis''' and '''time on X-axis'''.
|| We can see a plot between '''Time on the X-axis''' and '''Losses on the Y-axis'''.

This plot describes the power losses for the '''diode bridge''' varying with '''time'''.

|-
|| /* '''Simulation Setup''' Window */

Change '''Simulation Interval'''

Point to '''X-axis''' from '''0''' to '''0.1''' unit.

| | By default, the simulation runs from '''0''' to '''0.1''' unit time.

We can vary this interval using the '''Simulation Setup''' option.

|-
| | Go to '''Modeling Perspective'''.
| | To do this, go to the '''Modeling Perspective'''.

Click on the '''Modeling''' button at the bottom right.

Or press '''Ctrl''' and '''F2''' keys to open the '''Modeling''' window.

|-
|| Click on '''Simulation Setup''' option on the toolbar.
|| Click on the '''Simulation Setup''' option on the toolbar.

|-
| | Point to '''Simulation Setup''' window.
|| The '''Simulation Setup''' window opens.

|-
| | Change '''Start Time''' to '''0.01''' unit.
| | Here, change the '''Start Time''' to '''0.01''' unit.
|-
| | Ensure that '''Simulate''' check box is checked.
|| Ensure that '''Simulate''' check box is checked.

|-
| | Click '''Ok'''.
| | And then click on '''Ok'''.

|-
| | Point to the success message window.
