[COMSOL_Users] thermophysical properties such as thermal conductivity and specific heat, varying as a function of temperature

[Rogerio Brito]

Good afternoon,

I would like to know if there is the possibility of inserting
thermophysical properties such as thermal conductivity and specific heat,
varying as a function of temperature through the use of an expression, a
function of temperature, or even entering numerical data for a temperature
range in COMSOL? I like to put the properties as a site that I found on the
internet because I use a metal sample in my numerical simulations. We carry
out simulations of heat transfer by conduction. Site:

I appreciate the attention.

Hallo,

yes it is possible. you can name a function like lamda and apply that on comsol as "lamda(T[1/K])[W/m*K]"


or maybe you have it already in material library in comsol?

regards

In this case, are you using K[W/(m.K)]=T[K]?

Dear Rogerio,
it is very easy in Comsol 3,3.5 below 4 you should use "function" to interpole thermal conductivity
