Maximum number of iterations exceeded: 100 when starting from T0:300

I'm new to OpenFoam and I'm currently trying to run 3D case on the cluster.
The existing model is a Turbulence model, which we implemented with a suitable solver.
The solver and the model have just been verified for a 2D case and we can see that it works well. Now we have extended the geometry to 3D and we wanted to run the case on the cluster, but I always encountered the same problem, namely that the maximum number of iterations exceeded: 100 (I have attached a screen shot of the simulation).
Note this 3D model was carried out on our local workstation and worked ran well, but on the cluster the simulation crashes after 2 time steps. I ask for help if you know this problem.
Many Thanks,
Odai
