Vectors of high velocity
 

Hi all,
I quite new to CFD in Ansys Fluent, trying to model fluid flow in a fairly twisty pipe. Although the flow should not go above 40m/s, I find vectors of over 200m/s! I have tried many different models and settings, but it doesn't seem to be a problem with that. Don't know if its a simple problem to fix or if more information is required to diagnose.
