      Can you please provide more details here. What are you using? Is it Fluent Meshing or Ansys Meshing? 

      Regards,

      i know that is <0.1 is bad but i mean is it really affected the calculation and giving some error or it just make the simulation less accurate ?

      It depends. If those cells are in regions with high gradients you'll potentially cause the solver to fail and/or produce poor results. If not much is happening you might get lucky and nothing bad happens.
