Modeling Ice

Jennifer Myers · Tue Dec 04, 2007 3:20 am -1100

I am analyzing a wall system that is accumulating ice inside. Can I model the ice as a material in the wall system? If so, do you have any suggestions as to how to go about this?

Dear Jennifer,

if a porous material is accumulating water/ice you don´t have to care about. WUFI does it in the right way.

Or do you have that accumulation on a surface?

The wall system is concrete with an airspace, then insulation and gypsum board on the interior. There is ice building up to 0.5" on the interior face of the concrete.

Just use the air layer. It will be able to absorb water enough water and will treat it as ice if temperature is below 0°C.

Of course this is not correct but we don´t know a better way to treat air layers, the result are good and on the save side.

please see here fur further information about air layers in WUFI:
