A question about NS convergence!
 
If I don't use Multi-grid or other acceleration methods,can i get a convergence result?I means , can i get a residual ,for example, time derivtive of density in 10**(-4)~10**(-5)?

Getting a convergent method is of course possible without using special acceleration techniques. How far down you can get your residual is more a question of floating point accuracy.
