THERMAL CONDUCTIVITY FOR SOLID DOMAIN -BOUYANCY
I am trying to model a buoyancy problem for a roof composed of various sections. Unfortunately I have not even started because I can not set the following:
THERMAL CONDUCTIVITY OF THE SOLID DOMAIN
I have selected PURE SUBSTANCE, then CHT SOLIDS, then SOLID (thermodynamic state) and then I input the data, but I can not find where I should input the thermal conductivity of the solid... otherwise it will not run, I guess.
another thing is, I would like to run later this model more properly with radiation, but I need also to input the emmissivity of the solid... same case of THERMAL CONDUCTIVITY, I can not find the field to input it.
Last, but not least, till now I have not found the molar fraction for the concrete (idealizing this as 'one' solid only... of course in reality it is not that)... but since I wont run a species problem, I think I can override it... e.g use a value of ONE or ZERO... will this cause any problem during the simulation??
Many thanks for your help, whatever it comes is highly appreciated.

Molar fraction isnt relevant to the solid states AFAIK.
The thermal conductivity and emmisivity are all set in the material editor. Click the little (+) icons to expand the boxes.
