Hi everybody and thanks for your help in advance!
Im pretty new to CFD. I'm working with Star CCM+ and I have the following problem.

In my simulation I examine the flow around several spheres in a row.*

For my desired modeling I need to have my y+-values over 30.

I discovered a video from cd adapco already where they recomend to change

1) prism layer thickness
2) the streching factor
3) no. of prism layers

But no madder what I do, my y+ values still remain very low. Lowest way under 1.

Velocities I examine are between 0.1m/s and 1 m/s

Does anybody have some ideas which might help me.

Would be very great if somebody could suggest some ideas.

With the best regards,
