Conservative interface flux
 
Hello!

I am using the domain interface to connect two solid domains. I chose the conservative interface flux and set thermal contact resistance to zero.

Will it be right to say, that at the interface heat is described as follows: -k\frac{\partial T}{\partial x} = k\frac{\partial T}{\partial x} (the left side of the equation represents the first solid, and the right side represents the second), if heat conducts in X direction?

Any help is appreciated.

Regards,
Nurzhan

At the interface the heat flux normal to the interface is conserved; therefore, you must project the heat flux vector along the normal direction.

\left. -k\frac{\partial T}{\partial n} \right|_{Side 1}= \left. -k\frac{\partial T}{\partial n} \right|_{Side 2}

Dear Opaque,

could you please rewrite your equations as they are not appearing in the response.

Thanks.
