      If an object is not exposed to environment and is in contact with other objects with no gaps, will this object still radiate heat ? As conduction will take place but since its not exposed to any vacuum/air/environment from anyside.

      Hi,

      If you do not define any radiation boundary condition then no radiation takes place:

      17.6.2.19. Radiation
