Exclamation mark when doing Eigenfrequency study

Hi,

I`m doing an eigenfrequency study for the physics 'Heat transfer in solid', 'Solid mechanics' and the multiphysics 'thermal expansion'. My geometry is very simple, just a slender cylindrical rod. And I`m imposing a temperature gradient on a segment of the bar. But when I wanted to do the eigenfrequency study, I got an orange trianguler with an exclamation mark under "physics and variables section" for the 'Heat transfer' physics. Could anyone help me with this? I`m new to comsol.

Thanks,
Haitian
