Hi! Last time I encounter with high skewness in fluent meshing. Steps I do to cope with it:
creating scoped sizing and trying to match appropriate values to some parts of my detail (in this step I get bad skewness between 0,9 and 1)

Then I load my size field(here skewness become better, but still not below 0.85, only the number of bad faces decreases)

Sometimes I use diagnostics and quality and try to aggravate skewness, but you know geometry can be bad after this step or there will be some other mistakes in next steps

And the final step is wrapping. After this, skewness become better, but sometimes it still higher than 0.85.

So, I've spent a lot of time, but my problem doesn't disappear. Maybe, you guys can tell me some recommendations how to cope with it?

I'm generating mesh in fluent meshing. My model is a front part of race car. I fixed my geometry as best as I could, but it didn't help me)
