I'm new to OpenFOAM and I'm running my first simulation (not tutorial).
So in the controlDict file I've specified a startTime = 0, endTime = 0.5, and deltaT = 0.005.

The solver starts up and runs a few time steps and stops. What would be causing this to happen?

This is the last output from the terminal

I have since run the simulation with parallel processing, this is what I'm getting.

Starting time loop

Time = 0.005

Courant Number mean: 0.0557973 max: 22.1136
smoothSolver: Solving for Ux, Initial residual = 1, Final residual = 6.32534e-06, No Iterations 17

Time = 0.01

-------------------------------------------------------
Primary job terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
--------------------------------------------------------------------------
mpirun detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

Process name: [[10352,1],6]
Exit code: 145

This Co number is way too large. You have to reduce your time step.

That did the trick, thanks again for your assistance
