Hi

I want to calculate the value of ∇.(k∇T) when T=800 and use it in another equation. Is it possible using COMSOL? Can anyone help me?

Thanks
Krish

Hello Krish,
If T=800, then ∇.(k∇T)=0 .
Best,
Jeff

Hello Jeff,

Thank you for responding. I want to calculate net heat density (Heat in -Heat out) at each element in the domain when the temperature of that element reaches 800K. Is it still zero? And I want to use that value in other equation.

I appreciate your help.
