Beam path in Example 2 for melting the first quadrant of an annulus with \(r_{i} = 1\text{ mm}\) and outer radius \(r_{o} = 5\text{ mm}\). The entire beam path consists of 19 lines of length 4 mm. Each line is divided into 8 segments of equal length 0.5 mm. Only the blue part, \(\mathcal{C}^{\mathrm{s}}\), of the entire beam path is considered during optimization and the results from this optimization is then extended to the entire beam path. The path consists of 40 segments that are separated by the small ticks. The thin gray lines indicate the secondary path \(\mathcal{C}^{\mathrm{wd}}\).
