  4. 解析解： a b Problem statement

  5. u=-3 u=1 問題敘述(Bipolar外域問題) u=-2 u=2

  6. BEM直接法(case 1) Nelements=40,Nfield=868 Nelements=80,Nfield=868 u=-3 u=1

  7. BEM直接法(case 2) Nelements=80,Nfield=868 Nelements=90,Nfield=868 u=2,-2

  8. Nelements=400,Nfield=868 u=2,-2(Fichera法)

  9. 間接法之四種情況之數值執行(改BEPO2D) • 對比對應之MFS • 運算邊界通量 進度規劃

  10. 進度規劃 右圓 • MFS (Nobel) • BEM-BEPO2D (York) • Null-field BIEM-Y. T. Lee’s Software • 解析解 (York&Nobel) a b 左圓

  11. 左圓 右圓 B B B B’ B’ B’
