Re: UDF for Modelling Soldification using Enthalpy Porosity Technique

Hi,
I am writing UDF for Momentum (X and Y) and Energy to model solidification (isothermal phase change).
https://mail.google.com/mail/u/0/?ui...e680&zw&atsh=1
Attached is the enthalpy updating scheme.
When I run the calculation, the liquid fraction is not changing. Thus I deduced that enthalpy is not getting updated. I confirmed my doubts by using print commands at desired places and found that 'ap' is always zero.

I have attached my UDF.
Please HELP

Binary alloy solidification
 
Dear sir,

could you post some tutorials for simulation of binary alloy in fluent. I am simulating metal flow with solidification.
