Hello Everyone,

I want to model a 2D meltpool formed due to electrical discharge and the subsequent interaction of the meltpool with a flowing liquid (water). The description of the model is as follows: A film of liquid (water) is flowing over a solid metal surface. The metal surface is being melted at a location at the water-metal interface by the introduction of a heat flux. I want to see how the water interacts with the meltpool formed due to the heat flux. I am using built-in melting option in Fluent.

The problem with this model is that the interface while being coupled does not allow me to put a heat flux as a boundary in Fluent. If I change the interface surface (and/or corresponding shadow surface) from coupled to wall then I can add the heat flux but then the water zone and the metal zone do not interact with each other.

Is there a way to put a heat flux at the interface in Fluent? The heat flux I have is directed towards the metal only.
