How can i reduce the skewness in this meshing???

Hello everyone,
I had a problem with meshing when i tried to mesh a 2D geometry.
When I tried to imported the mesh into OpenFoam, I received the information that the skewness was quite high (max skewness: 4.3036) and this influented my results.

I want to ask you that how i can decrease the skewness number in my mesh in ICEM.

Thank you very much for all your helps!

You need to create a different block-topology for the lower half/ bowl-shaped part. See attached pic.
And you need to make the cuts in upper half perpendicular to the "walls"- just split the whole model first and then apply global grading (e.g. 1mm), then do the wall refinement.

Dear Matthias,

Thank you very much for your help!

Now, I can reduce the skewness in my model :)
