    Abstract: 研究發現,三維空間非結構性格點生成法常遇到如遮蔽、空洞、邊界破壞、區域外格體去除等問題,Advancing Front Algorithm發生空洞格體機會很大,而遮蔽卻大部份發生在Bowyer Algorithm法中。邊界破壞,區域外格體則多數發生在Bowyer Scheme生成法中。
    本文嘗試以Bowyer Algorithm建立不同外形。Bowyer Algorithm程序簡單,並擁有加點機制。文章中藉建立四種外形,證明Bowyer Algorithm在三維空間上的可行性,並提出防止遮蔽、空洞,檢查邊界破壞和區域格體去除的方法。由於非結構性網格的資料結構需求很大,作者採用C++程式語言作爲工具,可有效利用電腦資源及便利程序修改。
    本文結果證明Bowyer Algorithm能於三維空間中,對任意外形生成網格。其網格可利用於流場計算、射出成形模擬、心臟血管模擬等。
