Vacuum Comsol

  1. Feb 25, 2015 #1
    I'm doing a 1D thermal conduction simulation on Comsol Multiphysics 4.4 and my first component is vacuum.

    I did'nt found the vacuum in the material list.

    Should I create a new component with a null thermal conductivity ?

    Can't you select "User defined" for the thermal conductivity (instead of "From material"), and set it to 0? I've never used COMSOL for thermal conduction, but that's what I do for electrical conduction.
