Autodesk CFD Simulation Thermal Calculation with Eutectics (Ice)

Simulation Generality

Hello

 

I am a new user of the AUTODESK Simulation CFD software and I have a question for you.

 

What I mainly use is the thermal in this software and I want to simulate phase changes such as the transition from a solid to a liquid for a eutectic or simply ice.

 

My question is how to best set the material properties to manage this phase change?

 

I took into account the enthalpy for the case of the ice, but when I run a simulation, I find that the ice melts too fast compared to the real thing. So I want to find a way to get as close as possible to reality for my calculations.

 

I thank you in advance for your answers and hope that you will find a solution to my problem.

What do the conductivity  and temperature values correspond to in a straight line from 1 to 10?

What's the volume?

What is the ambient temperature?

What is the ATMO pressure?

 

@+ ;-)

Hello

 

I solved this problem myself.

My material was not properly characterized.

After providing as much information as possible, I arrived at a satisfactory result close to reality.
