Hi all, I am trying to simulate the water droplets impact on a solid wall and the formation of a liquid wall film. The continuous phase is air and the disperse phase is liquid water (I use the eulerian approach for the multiphase flow, not DPM). The wall film is taken care of using the Eulerian Wall Film model. The Fluent version I'm using is the 14.5.7.

Following indications from the on-line documentation and customer support engineers I set up a dummy DPM injection with the name of material the same as the material of the disperse phase, to which the string "-particle" is attached. Finally I initialize the film variables in Models/Eulerian Wall Film and hit calculate.

I observe max_cfl=0 in Fluent console during the calculation and I obtained null values of all the film variables (thickness and velocity). The model is not collecting any mass from the eulerian dispersed phase.

Has anyone else come across this problem and knows how to proceed?

Thanks a lot in advance.

Cheers,
Michujo.
