9. Before going any further, let us save our work. To do so, we click on the menu File and then on the option Save As. To save our work we must specify the path and the name of the file. Let us call our model Heat transfer. After doing this, we must click on the button Save. The file will be saved with the extension “mph”.
10. The next step is to specify the geometry of our system. The idea is to use as few figures as possible to define our system. For our case, the symmetry of the system allows us to use one single rectangle to define our model. Thus, to draw a rectangle we click on the menu Draw, then on the option Specify objects and finally on the option Rectangle. In the new window showing up we specify the size and the position of the rectangle we are drawing. Since we have to specify dimensions we must be careful with the values we will enter. The International System of Units (SI) is the default option. Thus, the dimensions of our rectangle will be 0.3 m and 0.05 m for width and height, respectively. The position is not important for this case and therefore we will keep the default values. After entering the values we click on OK.
