Some questions
 

Hi,all dears,
I have some questions:
1. I am simulating the flow structure around a vertical cylinder under steady current condition, the velocity of the current is about 3m/s, the height of the vertical cylinder is 14m, the depth of the water is 25m, the diameter fo the cylinder is 3m. The grid I use is fine enough, and I simulate the problem for 60 seconds. However from the streamlines I can see that it looks like a laminar flow more and the turbulence is not intensive. What might be wrong with my simulation?
2. I encounter with some messages given by the solver, but I don't understand where do the errors come from? I will show it below:

Usually this error is because the hard drive is full. Check that you have space. Otherwise, it may be related to your specific version, and I would suggest contacting FLOW-3D support directly.
