ratio for mesh sizes between two neighbor zones
 

Hi guys

in meshing procedure if I want to make mesh in different zone with different sizes then how much would be the maximum ratio of mesh sizes between two neighbor zones,

Thank you

Hi,
actually we use multi zone method to create mesh with locally ratio jump. but as a rule of thumb for good accuracy it's better to be under 1.06 .

very good to know, thanks, I thought it could be much much higher but I have to revise it according to your opinion
