✦ Synopsis
and is divided into five uniform segments. For the explicit scheme, the time sample was chosen as 0.053 LM. The Ž . current at the location 0.0; y0.1 is shown in Figure 4. Again, the agreement is good, and it is seen that for the implicit scheme, one can make ⌬ t large and violate the Courant stability criterion, and yet obtain stable results.
As a final example, we consider a circular cylinder center centered about the origin. The radius of the cylinder is 0.1 m, and for the numerical solution, the circumference is approximated by 12 linear segments. Figure 5 shows the current induced at s 0Њ with ¨⌬ t s 00.2 LM.
