yes it is the light blue.I have attached the airfoil data in a previous post if you need the vertices

[yoooodarulez]

I have divided the airfoil into 4 sections

[-mAx-]

ok then move your split points far from angle (ie: links)

[yoooodarulez]

I have deliberately put the split points in those exact spots because it was at those points that the skewed elements appeared in the first place.I will try moving them (to the left or to the right of the vertices?does it matter?)

[-mAx-]

far from trailing edge

[yoooodarulez]

So the triangle section of the wing will get bigger now(it will be like the outer triangle of ur pic) and i need a transition area aswell in front of it again?

Something like that (I alreddy see next problem, if you have refinement at the trailing edge)
Maybe someone with airfoils experience can give you more tips.
At the other hand, if you are not interested in this extremity, you can simply delete the adjacent volume

I have done something like that and im working on the final section, the triangle part the one i should 1 tri element mesh,but i dont know how to do so.The first section was meshed using quad pave and the other 3 using quad map.Till now the most skewed element is in the first section with a value of 0.39 or so.But i m wondering how can i choose only one element to mesh my section with

[-mAx-]

if you mesh the last section, the skewness will be around 0.9
But you won't be able to mesh it since you didn't create the transition.
To your question, you can try to sweep all this surfaces in z-direction. Gambit will generates the volume (and you will have to connect all surfaces to be sure, that everything is ok)
But your last split in trailing edge is to close from the angle, that is causing the skewness trouble
Else on your picture 5 you can delete the triangle surface, and you forget your trailing edge. Since your split is very close to the angle, it won't affect the solution

[yoooodarulez]

So basically even if i create that transition area and even if i mesh the last section,it will be of 0.9 skewness regardless the transition area?By transition area you mean the part before lthe triangle section meaning part 4 but it has to be meshed differently than what i did in order to be an actual transition section i presume?On your suggestion about dumping the triangle part,is it more accurate to just dump it than keep it along with its skewness?

it will give you less work

Here is the topology without meshes

Heres a new mesh
