Hello everybody,

I am very new OpenFoam user and am trying to simulate vortex shedding of a cylinder in crossflow. As of now I have started the case with simplefoam which solves for first 4 timesteps and then crashes giving the following error:

#0 Foam::error:rintStack(Foam::Ostream&) in "/home/stss5/OpenFOAM/OpenFOAM-1.6.x/lib/linux64GccDPOpt/libOpenFOAM.so"

I dont at all understand what this error means. It would be kind enough if you could enlighten me.
Thanks
