Simulating 1D Thermal Conduction with Vacuum in Comsol 4.4

Click For Summary
SUMMARY

The forum discussion focuses on simulating 1D thermal conduction in Comsol Multiphysics 4.4, specifically addressing the absence of vacuum in the material list. Users suggest creating a new component with a null thermal conductivity by selecting "User defined" for thermal conductivity and setting it to 0. This method is analogous to techniques used in electrical conduction simulations, providing a practical solution for modeling vacuum conditions in thermal simulations.

Hi,
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 ?

Thanks

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.
