Hello, 


For improving mesh after prism generation, you can use Fluent Meshing. 


In WB Meshing please export .msh file from File --> Export


Start Fluent in mehsing mode. Read .msh file. Go to Mesh --> Auto Node Move. 


Select all boundary zones and click apply. 


On prism layer thickness: it depends on what y+ you are targeting, what velocities you are using etc. 


In general 5 layers of prism layers should be enough for regular flows. Please try to reach aspect ratio of 5-10 for first prism layer. 


Regards,


Keyur
