How do I assign an intial velocity profile with boundary layers already present. I can only seem to assign a constant velocity and then let the boundary layers devlop. I with to assign boundary layers in my profile initially.

thanks

I think you need to use UDF. Check the UDF tutorial.

there is an UDF example for this. The actual profile will be seen once you start iterating. check with display->vectors.

You need to make a file with velocity profile, and use profile function to read the file, then you will see it in the boundary option.

Check this link from google:
