Hello Guys, 

I am trying to mesh the prototype hood of a car as per the specifications below:

S.N Quality Criteria  Value 
1 Aspect Ratio  5
2 Skewness 45
3 Warping 15
4 Taper      0.5
5 Min. Length 2 Units
6 Max. Length 8 Units
7 Min angle Quad 45
8 Max angle Quad 135
9 Min angle Tria 20
10 Max angle Tria 120
10 Tria %  10

When performing mesh along the fillets, I am not getting the desired warping 15. 

How to construct lines in a fillet region to get a proper mesh flow? 

I was able to manually edit the elements to get rid of the other issues except warpage. I tried translating the elements to get rid of the warpage problem however the elements surrounding it also started to have warpage issues if i adapted to this translation method.

Should i construct a line in the fillet region to get a proper mesh flow? what other topological modifications can i make to get a proper mesh flow there?
