Without inflation, my skewness is just fine. It is about 0.84. But I need to capture the near wall effect. Inflation is needed. But after adding inflation, skewness just increase.
This is the picture of it. The circle part is causing the problem.

I tried slicing them and only focus on the middle surface. But the skewness is still bad.

Basically I am trying to improve to mesh quality.
I am simulating a plate heat exchanger. I'm new in cfx and just trying to seek for some help. Other forumer suggests that I add inflation at the interface of the fluids. But the inflation layers cause bad quality mesh. Hope this explains.
