圖1.根據函數 Energy(t) = 90000*sin(t) [W/m3] 設定正弦變動熱源所需的 Fluent UDF 程式碼 即使UDF 不大 (如圖 1 中的函式),也需費心思考才能建立起來。例如為了建立這個 UDF,工程師需進行單位轉換、以 C 語言進行程式設計,並學習 Fluent 特有的編程概念。 這些概念包括但不限於: 執行序 (Fluent UDF...
The UDF DEFINE_PROPERTY allows the user to modify only the laminar thermal conductivity. For turbulent flows, FLUENT computes a turbulent thermal conductivity based on turbulent viscosity and add it to the (UDF-defined) laminar conductivity ? #define #define C_K_T(c,t) (C_MU_T(c,t) * ...
TIPS & TRICKS USING THE 6 DOF MODEL An ice cube makes our drinks so much more refreshing but have you ever wondered if the ice cube will touch the bottom of your glass as it falls in. Being able to model a solid falling into a fluid would benefit many industrial applications. This ...
