Thanks for your replies!
I use simpleFoam > log
For initializiation I use potentialFoam and switch then to simpleFoam. Didn't know the Courant number ist then meaningless. Thanks for the information :)
I want to simulate the lift and drag coefficient od an airfoil. Is it Ok to use SimpleFoam or should I use a different solver?
My log file looks like this:
