我有一个问题如下。
有一个圆饼形（如一个硬币）电阻，在通电流的时候有热量产生在电阻内，电阻放在空
气中。如何求电阻中的热量分布。
我的问题主要在于如何定义由电流产生的热量。我是个绝对的ANASYS beginner。我也
在看ANASYS的书，大步分求热量分布的都是在一个已经固定的温度环境中求物体的热量
分布。这个电流产生的热量导致温度变化是随时变化的。请大侠帮忙啊
万分感谢。

Is this your home work?

no. This is one small thing I have to calculate in my dissertation. My
research is nothing to do with ANSYS. I just have to plot one figure about
the heat distribution. Thank you for reply anyway

I haven't use Ansys for 10 years, don't know how it works anymore. Basicly
you need to use the static electrical solver, define two current boundary
conditions,one in, one out, with same amount of current, and solve for the
current distribution. Voltage condition works the same. You can plot your
current distribution as heat distribution, they are the same.

Thank you for telling me where and what I can look for.
