Problem about Thermal Conductivity Calculation

Hello,

I am currently working on calculation of thermal conductivity of a kind of epoxy (DGEBA and 33DS) under different temperatures (for example: 300K, 400K and 500K). I use the thermal conductivity script. From the literature, I notice that usually the thermal conductivity of the epoxy resin should increase over temperature. However, in my result, it seems the thermal conductivity decreases over temperature. The value of thermal conductivity in the Summy sheet is the same as the last value shown in the Analysis sheet. I wonder if that value in Summy sheet is the one I should use as the final result? Does anyone have any idea on this problem? Thank you!
