might limiting of velocity have a unsuitable effect on results?
 
i have a subsonic problem but velocity at early time steps goes higher than sonic velocity and so i've limited it to sonic values.
I have a doubt about the effect of this work on last results.
Because running takes much time i decided to ask first.
The CFD problem is unsteady compressible if important
