求ansys移动热源如何建立，求相关实例！！！

做的是磨削温度的有限元分析，求ansys移动热源如何建立，求相关实例！！！

Answer 1

给你一个三维平板焊接的实例，用的是移动高斯热源。主要是这一段：
! Begin of equation: Qm*exp(-3*({X}^2+({Y}-V*{TIME})^2)/R^2)

/PREP7
!定义焊接参数
L=1E-1 !焊件的长度
W=1E-1 !焊件的宽度
H=6E-3 !焊件的高度
U=20 !焊接电压
I=160 !焊接电流
V=0.01 !焊接速度
YITA=0.7 !焊接热效率
R=0.007 !电弧有效加热半径
Q=U*I*YITA !电弧热功率
Qm=3/3.1415/R**2*Q !加热斑点中心最大热流密度
