1.Using triangle coordinates to integrate the piecewise function by hand or
symbolic calculate software.
2.But I guess is your problem is not very special, there are a lot of standard
solution available on finite element analysis textbook or somewhere else. Try
to search keywords “triangle element” “FEM” “finite element analysis”

: 很久不用差不多都忘了,回头查一下看看能不能解决.

You can integrate over n small 整个一块的polynomial and calculate the sum of n
results.
Or slice that piecewise function and make element finer to make sliced
function over every elements 整个一块的polynomial.
I remember lame Numerical Manifold Method deals with a similar case.
【在 k****g 的大作中提到】![](/moin_static193/solenoid/img/up.png)
: 可是在每个单元里不是整个一块的polynomial,是piecewise的
: 所以用一般的quadrature方法都得不到精确解的。
