Hi. I have created an structured O-type mesh as can be seen in the first pic. I read that AR can be up to 10,000s in the boundary layer as wall-normal velocity grads are much larger than streamwise velocity grads. The white dot in the pic shows where AR becomes almost 1. In the second pic you can find more see the AR is large only very close to the wall. Do you think that this a good mesh?
