Heat-moisture coupling, condensation

Hello,

I am trying to evaluate one building foundation detail.
My goals are to:

1) generate thermal fields in time
2) determine the moisture concentration inside the construction
3) find out if there will come to water condensation and if so, when and how much water will condensate

I have done some thermal simulations before using Heat transfer in solids physics, but I am not sure what physics to use now. I suppose, I will have to use some coupled physics (probably Transport of deluting species with temperatures comming from the Heat transfer in solids) but I am not quite sure.

I have seen this post: www.comsol.com/community/exchange/11/
but unfortunately, it is in an old Comsol version and therefor I can't open it.

Thank you in advance for any kind of help
