Does anyone use the eulerian wall film model ?
 
Hello everyone, I am trying to simulate the behaviour of droplets impacting a wall by using the DPM model and eulerian wall film model. The droplets will form a wall film eventually.

I dont know which part is wrong, but once the droplets contact with the wall, Fluent crashes showing "divergence detected in AMG solver:temperature".

Does anyone could give me some explanation how to make it work? Any help will be appreciated.

my procedure:
1.enabling Euler-Wall-Film.
2.setting the wall DPM BC as a trap and switching to initial condition with all values as 0 in wall film setting.
3.at models minimuming film-thickness to 0, initializing it.

I have exactly the same problem, cannot figure out what is wrong...
