Aspect Ratio base algorithms for Boundary Layers
 

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
