Courant number
 

Dear friends,

When I use VOF mode and pressure-velocity coupling , I find the default courant number in Solution panel is 200 and the default global courant number in Iterate panel is 2. I can find the definition of these tow courant numbers in Fluent Documentation but I still don't know how to make a good agreement between these two courant numbers when using VOF mode.

Thank you in advance!
