TUI命令

1、TUI 命令基本认识

Fluent 中的 Tui 命令能使 Fluent 自动化操作，包括文件设置、案例读取、参数设置等功能。

2、基本操作

在 Fluent 中的命令行可进行 tui 命令操作

• 回车可查看命令提示；
• q：返回上一级

3、案例

案例中包含注释

; 1、读取网格文件
rc fluent.msh
mesh/check
mesh/quality


display mesh-outline

; 2、勾选瞬态
/define/models/unsteady-2nd-order yes

; 3、设置重力加速度
/define/operating-conditions/gravity yes 0 -9.81 0

; 4、开启能量方程
/define/models/energy y y y

; 5、湍流模型
/define/models/viscous/spalart-allmaras y

; 6、新增混合气体
/define/models/species/species-transport y hydrogen-air
/define/materials/change-create hydrogen-air hydrogen-air y 2 h2 air 0 0 n n n n n n

; 7、管道材料及土壤材料
/define/materials/copy/solid/steel
/define/materials/change-create aluminum soil y constant 2650 y constant 789 y constant 2.9 y

; 8、设置边界条件
/define/boundary-conditions/fluid solid fluid no no no no no  0 no 0 no 0 no  0 no 0 no 0 no no no no yes no no 1 no 0 no 0 no  0 no 1 no 0 yes no 245000000000 no 245000000000 no 245000000000 no no 502000 no 502000 no 502000 0 0 no 0.43 constant 1 yes no no no

/solve/report-definitions add report1 surface-vertexavg field molef-h2 surface-names point-1 () q

/surface/plane plane1 0 0 0 0 1 0 0 0 1

; 10、初始化
/solve/initialize/set-defaults/ temperature 288.15
/solve/initialize/set-defaults/ pressure 0
/solve/initialize/set-defaults/ species-0 0

/solve/initialize initialize-flow ok
; 显示一下contour
