Problem with transient simulation of pump inner flow by pimpleDyMFoam on 1.6-ext
 
Hi all,

I have a problem regarding running of a pump case with pimpleDyMFoam on OpenFOAM-1.6-ext.

After I have set my case, and using the "pimpleDyMFoam" command with single core on my computer, and the computation was quickly stopping with the following information:

I don't know what's wrong with my case or the solver. Can anybody suggest me some hints?

and the constant/dynamicMeshDict, system/fvSolution, system/fvSchemes, and system/controlDict are attached!
