UDF: Metal Melting in Discrete Phase
Hello everybody,

i want to simulate the melting of metal particles with the discrete phase model. Does anyone have an idea how to implement such a problem with UDF?

I figured out two options but none of them seems to be praticable:
- Treat the metal particle as an inert particle (Inert heating law) and add somehow fusion heat when melting temperature is reached. Problem: How to add fusion heat? to which fluent parameter? temperatureupdate makes no sense here...

- implementing a routine such as evaporating. problem: dpm evaporating is based on mass update (bc mass loss of the particle). metal melting has no mass loss: melted mass sticks to the particle

any ideas?
