Is snow material available in COMSOL library? If not, how can I generate the same.

There are so may types of snow with varying crystal size, moisture and density. I would use properties of ice the properties of which you can google. Snow is "porous ice" with pores filled with water or air.

Interesting question, though :)

'Porous ice' may be a useful approximation for electromagnetic properties but probably not for acoustic properties.
There is some literature on the topic, e.g. arxiv.org/abs/1502.01284 and eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/20232/1/A20_p23-63.pdf

I am sure you can find a lot more. The last resort is certainly to measure the properties you need in snow samples.

Cheers
Edgar
