Hey @dschroeder, you owe this post mate 
Thank you for hitting a big reply button here. Don’t worry, I enjoys reading on aerodynamics and CFD. Hoping that your projects are hitting success.
Happy to see @Ricardopg back. I have a question please:
If I go for full resolution wall turbulence approach, at which Y plus I should stop the boundary layer meshing? Is it necessary that the last grid cell should not cross y plus of 5 or laminar sub layer? If so, whether the log law region will be kept out of calculation? Actually everybody says the first grid cell must be within y plus of 1 but it really confuses me on the y plus value at which I should stop growth of boundary mesh layers. @dschroeder already gave an answer to me but I just need a confirmation from you both.
Thank you all for being here!
