Hi
I modeled a simple box in Star ccm+
and choose

3-D
Implicit Unsteady
Ideal Gas
Segregated fluid Temp.
Laminar
Thin Film
and Deicing

models. And in a boundary condition I enabled Ice Layer Option and put thickness value in Physics Values.
In temp. contour, temp. stared from 260 k and reached 300 k. But Ice Layer Thickness contour was not changed and was the initial value that had been set. What is wrong with this modeling?

Thanks
