Hi,
I've been struggling with this problem for past few days.Kindly help if anyone has some ideas.

Problem(star CCM+):
There is a windshield with a heating pad on the inner side(towards passenger side) and a thin layer of ice on the outside surface.

Ice and windshield are at -20 C initially and heating pad generates 30W.
Ambient : -20C ;Pressure :1atm

VOF model and Eulerian multiphase model with a single phase (water-ice) are used with const density..viscosity and therml conductivity are modelled as field functions based on "relative solid volume fraction of water-ice phase". specific heat is a field function based on temperature.

Afetr running transient simulation I'm getting visibility and temperature on windshield as shown in the fig.

From the fig we can see that it is superheated steam above heating pad,but that heat is not getting transferred to ice nearby though I've defined interfaces as well.

Please help!

Shyam
