[開發教學(英文)](https://www.bilibili.com/video/av48157570/) [開發教學(中文)](https://www.bilibili.com/video/av48009574/) # P.S. 1. 使用caelinux的模型轉換需仰賴手動:從cad轉換成solver所認識的模組需要手動去設置範圍,導入演算法計算範圍後設定網格、發熱源,才能讓solver看得懂並做運算。 2. Abaqus具有完整的二次開發,使用語言為python,開發環境完整,資料眾多,但是軟體費用昂貴。 3. FloTHERM的二次開發較為簡單,使用vba,可以在改變簡單參數的情況下批量輸出(簡單參數:cube大小),但能設的參數較少(在參數很多時vba容易崩潰)。 4. Icepak的二次開發使用TCL,能調整的參數很多,但開發需要的時間較長。 5. 建議一條龍開發,
