sina_mech Senior Member SinaJ Join Date: Nov 2009 Posts: 136 Rep Power: 16	I get a strange result. When I use Second Order pressure scheme, I get a very good residual convergence, but Streamlines don't look fine. and when I use PRESTO! I have non-converged residuals (converged up to -3 or -4), but streamlines make much more sense. Does anybody have any explanation for this? Thank you wc34071209 likes this.
