Hi,

I want to use rhoSimplecFoam for a two-phase-flow. One phase is air, so I took the tutorial as basic. The other phase is a fuel mixture, which is injected into the air stream. Now I have used setFields for the injection canal. SetFields works, but when I run rhoSimplecFoam, I get following error:

~/OpenFOAM/.../rhoSimplecFoam_...$ rhoSimplecFoam >log

It seems that there is a problem with thermophysical properties.
Besides, I didn't really understand the combination between setFields and rhoSimplecFoam. When I use setFields for two phases, what is the mixture specification in thermophysical properties for?
Can someone please help me? I would be glad about papers or cases, in which this combination is explained.

Thanks in regard.
