I'm CFX user using LES which is turbulent model..
first attempt, minimum grid size is 1e-6 in used domain.
calculation is complated.
but......because of the problem of the y+ value...
I adjusted minumum grid size = 4e-7
and then contect error. floating point overflow..
possible minumum grid size for CFX solver...exists?
Sorry. please understand my English skills..
I look forward to your reponse.!!!!!

I don't think there is a minimum size for the elements or CVs. At least not in the range of 4e-7.
However, reducing the element size from 1e-6 to 4e-7 increases the number of nodes in a 3D grid approx. by a factor of 16. So if your original grid was already relatively large, maybe this could be a reason for the problem.
