Hi,<\/p>\n

I have used iso-surface using expression<\/strong> and quadric surface<\/strong> to created side surface of a cylinder. But both created surfaces are not that smooth in the middle and appears many black and grey spots as shown below. It’s weirder that the spots only occur in the middle while both side of surface circled in red are smooth. And it is middle region that what I want to visualize. <\/p>\n

<\/p>\n

  Both side surfaces created in two ways have same problems and it have influenced contour display.<\/p>\n

<\/p>\n

I want to know how to resolve this problem or I have no choice but to turn to tecplot the like.  I  prefer Fluent to do post processing .<\/p>\n

Any suggestions is appreciated.<\/p>\n

Best regard.<\/p>\n
