Hello, I would like to know
 
Hello,

I would like to know what is an acceptable limit value for the ratio of the maximum to minimum edge length? What are the consequences of having a wide range of cell sizes in the mesh?

Thanks.

According to Benjamin Martinez over 2500 it become a problem For wind simulation. See page 26 of is thesis.

But I'm guessing that it depend of the simulation your are doing.
