When you have an unsteady simulation you have the field function Convective Courant Number available.
You can either create a scalar scene displaying that. Or if you want to diplay the max courant number create a max report and plot in your region using Convective Courant Number

Send a message via Yahoo to nimasam
in log file, you can see courant number value but if you want to plot courant number vs time you should use foamlog command

Hello!!

hmmmm......well.....I still don't know how to check the CFL number in Fluent.......I'm carrying out my first unsteady LES simulation with FLUENT 12.1 :-)

Can anyone explain it a little bit more "for dummies" like me?

Thanks


:-)
