2D flow over a Bump in channel

I am currently trying to run a validation case of flow over a 2D bump in a channel, using simplefoam with the k-omega SST turbulence model. I am having trouble getting the results to match the existing results by NASA at the following website, http://turbmodels.larc.nasa.gov/bump.html. The analysis looks like it is going to converge and then after 2 to 3 thousand iterations taking most of a day the time step continuity errors blow up .
Attached is a picture of the skin friction coefficient before the blow up, the same result occurs during the entire length of the simulation, so something is obviously really wrong, I just cannot figure out what The grid was generated by NASA so I think it is safe to say that the grid is not the problem. Attached is the zipped file, any help or suggestions would be greatly appreciated. which has the boundary conditions file and all of the system files I have used

I think you should contact
he was solving this kind of problems with simpleFoam.
