steadyCompressibleMRFFoam is solver which is part of foam-extend-4.0
I tried to use it with standard tutorial mixerVessel2D, but solver stops after first time step and there is no error mentioned in Terminal. However after some time I do get message from Ubuntu that solver had stopped.
Here is all I get from Terminal:

I'm attaching my case files. Can someone please take a look what is wrong and run the simulation. Maybe it's just a problem with my installation of foam-extend. I installed it recently.
