Hi Everyone,(adsbygoogle = window.adsbygoogle || []).push({});

I have a thousand data points that create a graph of Copper's Thermal Conductivity as it changes from a temperature of 4.5 K to 300K. These points create a somewhat bell-shaped curve, and I have been trying to find the equation to this curve so I can integrate it. I have previously tried to solve it by hand but I got the feeling I was going about this whole thing all wrong.

In the end, I would like to model this piece of copper undergoing a change in temperature of 295.5 K. Normally, it would be easy to do this using Comsol, but the change in conductivity is not linear due to the extreme temperature change.

My question is: Is there any way to upload, or import, the data points into Comsol? I'd like to have it find the equation or find the area under the curve So I can model this piece of copper.

Appreciate the time,

Mike
