Can i know how to reduce the skewness in GAMBIT?

by knowing the reason of skewed elements....
and then correct the parameters or topology

Hi. I generate tet mesh with size function to create a mesh with more density on the solid-fluid interface. My mesh has 143 elements (0.02%) that are silver and their skewness is in the range of 0.95-1.
Is this skewness leads my results into inaccurate solution or it's OK?
If so, How can I reduce the skewness?

I'll be thankful for any advice.

check where are those cells localized.
If they are in the same area, then for sure you can fix the problem with some mesh settings
