Hi all,

I was running a Direct-injection case which has a side-mount fuel injector setup, like most common DI engines available today. The fuel injectin event started at -299 degree ATDC and continued receiving unreal large amount of stuck film warning since the begining of injection.

I have noticed that a former thread which mentioned nearly the same issues: Warnings in IC engine simulation

Unfortunately no solution has been provided from this thread.

I have checked the geometry from case by diagnosis mode and everything seems fine. The solution timing is a variable timing as most Converge example case did. The fuel injection setup is identical as the available Converge GDI SAGE model.

As looking closer to issue, it seems that it would generate a stuck parcel warning if the fuel parcel hit the cylinder wall. As the dynamic mesh started to trim when piston moving up, those stuck parcel will be gone instead of vaporize or burn.

Please comment and share your thought about this issue. Thank you.
