Use FGEM. See lib. case V201. Or use Null object to create region of your interest.

Re: about the grid
 
I have tried many times to use Fine Grid Volume. Unfortunately, I have many problems with that. First of all, in VR-Viewer when I click on the 'Vector toggle' , the vectors are completely wrong. They have random directions and when i have zero angle of attack there is no symmetry What can I do ?
