Smooth circle in gambit

February 20, 2008, 11:40

Hi All,

Im trying to model, for example, flow around a cylinder, but when I create a circle and apply a boundary layer the outward gridines seem to cluster in groups. Any ideas on how to get the gridlines regularly spaced? Please see http://img100.imageshack.us/img100/3...oundarybr5.jpg for what I mean.

Sorry if the solution is simple, I'm a real beginner here!

partition the domain into 4 quarters, and then use quad mapping

Draw the square in center of circle and divide the remaining circle into 4 parts of 90 deg sectors.
