Load or Temperature Assignment to Nodes

Hi All,
I utilize Livelink Matlab to solve a multiphysics problem. First of all, my Comsol model solves film pressure on a surface. Then, I extract the pressure distribution and film thickness of a boundary for every node to Matlab environment. I created a code that solves energy equation for temperature distribution by utilizing the pressure and film thickness obtained from Comsol (I use mpheval function to extract the pressure and film thickness from Comsol model). I want to assign temperature values to Comsol model again to solve the problem with temperature boundary condition (or as external temperature for heat flux boundary condition). Is there any way to assign temperature values specifically to nodes? or do you have any other suggestion to apply temperature to a boundary?

Thanks for your great work and precious help!
