However, I find some irregularities in the velocity contour at locations with highest skewness (second picture). Now I&#039;m worried about another geometry with a bit higher max skewness(&lt;0.75), and whether that will give me acceptable results or not.<\/p>\n<p>Can this issue be solved by changing any of the simulation parameters? Or changing the mesh (which I&#039;d rather not) is the only way to fix it? <\/p>\n<p>Thanks \ud83d\ude42<\/p>\n<p><\/p>\n<\/p>\n<p>p.s.
