error message with interFoam

I am trying to implement interFoam for a falling film on a flat plate but I am getting an error message which I dont understand. Could someone please help?

Hi Ovie

Without having seen what's immediately prior to these errors, my guess is that you time step gets smaller and smaller, hence the crash is simply a symptom on the fact that your computation is diverging.

Bests

Thanks Niels,

I went back to review the tutorials and figured that I had to execute setFields prior to running the computation. Problem solved.

One quick question, do you have any idea if its possible to implement the MULES solver for volume fraction variable in steady state?

Thanks again.
