• passive sides: 1-2, 2-3, 3-4
• npoint: 10
• nelem: 3
• nptr: 9
Next, the chosen side is 2-10, but the circle with centre K ideal now contains node 9
(Fig. 8.30) and so this is used as the vertex of the next element. The updated front is
shown in Fig. 8.31 with properties:
• active nodes: 1, 9, 10, 4, 5, 6, 7, 8
• active sides: 1-9, 9-10, 10-4, 4-5, 5-6, 6-7, 7-8, 8-1
• passive nodes: 2, 3
• passive sides: 1-2, 2-3, 3-4
• npoint: 10
• nelem: 4
• nptr: 8
