Dear software-mates, It is good to know that Materials Library of COMSOL has over 2,650 materials. But I found it difficult to search for the only one material I want, that is the most common kind of light-weighted concrete, or areated concrete, or AAC/NAAC in short. I have checked the concrete type, but can' t recognize something like that. If anyone have any idea about it, please let me know. Little hints are very welcome!

-------------------
keep pushing forward.

You might have a better chance of getting hints if you told the community which material properties you are after!

Thanks for this little hint! The material I' ve been looking for is the most common kind of aerated cellular concrete with density lower than around 800kg/m3 because of the air-voids in the material, (normal voidless Aerated concrete can be produced in a density up to 1800 kg/m3). I don' t want to make the issue complicated enough to build the inner structure of this cellular material, so I' m just simply looking for this in the given list. If there isn' t one suitable, I think I will set myself,,,

Hm, you still didn't tell which properties you need ...? Mechanical properties like Young's Modulus, Poisson ratio? Or electrical properties like conductivity, permittivity? Thermal properties, whatever? What is your modeling approach about?

I see, I' m going to model on the process of acoustic wave in the air penetrating a double-layered wall made of areated concrete. Taking it as a premodelling, I think the best way is to find a material already existed in the list. If there isn' t, I will search the properties and then build it myself. Thanks for remindness!
