ri2,OK；

(4)Main Menu>Solution>-Loads->Apply>-Thermal->Convection>On Nodes,选择Pick All,

在Film coefficient框中输入-2,在Bulk temperature框中输入100,OK;

(5)Utility Menu>Select>Everything；

(6)Utility Menu>PlotCtrls>Symbols,在Show pres and convect as菜单中选择Arrow, OK; (7)Utility Menu>Plot>Nodes；

18、恢复工作平面及坐标系统

(1)Utility Menu>WorkPlane>Change Active CS to>Global Cartesian；

(2)Utility Menu>WorkPlane>Align WP with>Global Cartesian； 19、设定载荷步选项:

Main Menu>Solution>-Load Step Options->Time/Frequenc>Time and Substeps,在Number of

substeps框中输入50,设置Automatic time stepping为On；

20、求解:Main Menu>Solution>-Solve->Current LS

21、显示温度分布彩色云图: Main Menu>General Postproc>Plot Results>-Contour

Plot->Nodal Solu,选择Temperature TEMP。
