When we have to make a new model, first <strong>of</strong> all we should decide if we want to make it in<br />
planar <strong>of</strong> axisymmetric. Choose it wisely, because it may save you a lot <strong>of</strong> time if the model<br />
can be made in axisymmetric type.<br />
When we have the plotted field values, we can use them to analyze the property along a<br />
contour. A contour is a line or region that we are interested in. Then we can compare it with<br />
the theoretical values. If those values match, it means the model we have made is correct. If<br />
they didn‟t, then we have to look deeper into the model <strong>and</strong> find out what has gone wrong.
