Hello, everyone!
I have a short question as shown in the title. Suppose a temperature field is solved. T(x,y,t).
I can plot 2 contours e.g. c1: T(x,y,t)=20 and c2: T(x,y,t)=30. Right now I wanna calculate the area surrounded by these 2 contours, so that the result will be time-dependent area S(t).
Does anyone know how to do it?
Thanks a lot!

I guess you can use logic conditions to do that, e.g., f*((T<T1)&&(T>T2))

Dear Zhang,
I appreciate so much for your hint. It does work for me.
BTW, do you know how to calculate the length of the contour c1, so that I can have L(t)= length of c1(t).
Thanks again!
