July 21, 2017, 05:23	An Issue with My Melting&Solidification Model When Using VOF	#1
AlvinF New Member Yiqi Feng Join Date: Jul 2017 Location: China Posts: 5 Rep Power: 9	Hi all, recently I want to simulate the process of powders melting and solidification using FLUENT. Firstly I build a simple model to test my UDF. The Model after initializing is showed below. But there is a problem. I want to add a heat flux boundary condition on the bottom, but there isn’t the flux where the solid phase appears. I don’t know why it happened. Could you give me some advice about this problem?
