The inflow/outflow condition cause the NaN problem about incompact3d

[GoogleCodeExporter]

Dear Ye Zhaoliang,

If you want to change the BC, then you need to change numbers of mesh nodes as 
well. If you want to use inflow/outflow then you need to define them of course 
and you need to pay attention to the flow rate. If you want to do a spataially 
evolving channel flow you will have to take a huge domain in the streamwise 
direction if you want to have a chance to get a turbulent state. If you want to 
do that I will suggest a recycling procedure.

Thanks for your attention.
I have three questions about your answers.
1: what does you mean about the flow rate? the range of the flow rate?

2: Take a huge domain in the streamwise direction -----> 128? 1535? Maybe you 
can give us a story about the huge domain.

3: Please forgive my ignorence  and satisfy my thirsty for knowledge. What does 
it mean the recycling procedure？
