Finding the average on a cut plane

Hello,

I have a geometry on 2D which I have extruded by 0.02m. Now i want to know the average of the temperature at 0.01m. I know I can use the cut plane feature to get the plane but can anybody help me on how to get the average temperature on that cross section?

Thanks,
Asghar

Hi,

I would suggest to integrate across the plane and divide by the area.

Hi,

Thanks for your reply. I'm a beginner on comsol. Sorry if this sounds amateur. After getting the cut plane, how do I integrate along it to get the average temperature?

In the Results section under Derived Values add a surface integration node, select the surface you want to integrate across and the expression you want to integrate.

Hello,

Thanks for your help. I have got the average temperature in m^2*K. Now I need the area which is quite complicated to calculate. Does comsol have any function which calculates the area?

Can I use the average function to do the same thing? But what I have seen is that to use the average function, I have to compute the solution again. Is that true?

Thanking You,
Asghar
