The working fluid is a multiphase one so that the air contains supercooled water droplets (i.e., the secondary phase).
The problem is to accumulation of the secondary phase on a wall and then simulate freezing of that region.
Notice that the diameter of the droplets is given which can be set in the Eulerian multiphase model, but the Solidification/Melting model is not available when using the Eulerian model.
The Solidification/Melting model is only available for the VOF model; but the droplet diameter (i.e, MVD) could not be set for the secondary phase option.
How could it be doable using FLUENT?
Any ideas would be appreciated in advance.

Hello,
The freezing presents the solidification process. but, why you use a multiphase fluid? if you should do that, use the VOF model and add the droplet diameter via a UDF.
Thanks, Hayder Ibrahim Mohammed
Since the air contains super-cooled water droplets, the working fluid is multiphase.
Unfortunately, the VOF model naturally considers the phases as two immiscible fluids, thus, adding the droplet diameter (MVD) does not fit with the model, and could lead to erroneous results.
The diameter can be set in Eulerian (or its simplified model, the Mixture), whereas the solidification model is not accessible in them.
