Hi everyone,
I have a question related to velocity profile on Flat plate. Could you tell me how to get a minimum variation between the simulated simulated solution and analytical solution of Blasius equation?(please see the attachments)

The velocity should be increased from zero at the wall to a value of 99% free stream velocity then keep constantly at free stream velocity. However, as shown in the simulation, the difference is over 5%. I have tried to do a finer mesh and lower convergence criteria but it does not help much. I will be happy for any help you can provide. Thank you!
The Nguyen,
