Hi everyone,

Is it possible to monitor Courant number during transient simulation in ANSYS FLUENT?
Generally, I'm analyzing wind turbine in ANSYS FLUENT. Simulation is transient, PRESSURE based solver with sliding mesh option (Whole geometry consist of two part: rotational domain which rotates at 72 rpm and stationary domain).Basically, for the better convergency, Courant number should be less than 1 in every element during the simulation. But I can not find the way how to monitor the Courant number, like monitoring the residual, drag etc convergence.

Looking forward to your reply.

Many thanks

There are two variables named cell-convective-courant-number and cell-acoustic-courant number.

In the GUI you will find it in the Velocity category.

Create a volume monitor for the maximum courant number that you like. It's not very var away from where you would create a drag monitor just look a bit farther.

Thank you. It works.
