How to introduce an interfacial thermal resistance between two materials.

  Hi,
  I am modelling heating effect on illuminated metallic nanotip (coupling DGTD+HEAT), the model works well, the only problem that I have is how to introduce the interfacial thermal resistance between a metal and a dielectric in the model.
  Do I have to add a thermal resistive layer of 0.5 nm or 1 nm with a low thermal conductivity or another way but I do not see any possibility of adding an interfacial thermal resistance.
  Do you have any idea for solving this issue?
  Thanks in advance for your time and help.
  Best regards,

  The solver automatically counts the thermal resistance at the material interface, since their heating property is not the same. Please refer the solver physics https://optics.ansys.com/hc/en-us/articles/360034917713-HEAT
