How to use UDF to get the Global courant number at time in fluent 14.0?
 

Dear everyone:
I used the fluent 14.0 to simulation the transient welding pool, in which I applied the adaptive time step(transient VOF model). I set the Global courant number to 2.And the Global courant number is also been solved and displayed in simulation after every time step in the message window.
If I want to get the Global courant number at time by UDF, how Can I do?
Best regards !

If Fluent doesn't hold the current global Courant number in a variable somewhere then you could find this value yourself. Loop through all of the nodes or cells and find the highest value for this Courant number.
