eleazar Member Elena Cortin Join Date: Mar 2009 Location: Paris Posts: 65 Rep Power: 17	Hi, I have a case that been asked to create Boundary layers based on the element aspect Ratio 1) Why in CFD to do that? what about Y+ ? 2) If the Height will be 5% of the lenght of the element then the First element thickness have to be very big, so the Y+ is not ogint to be 0 to 1. 3) Which mesh engine support this BL creation? Any help? Thanks
