Imported Geometry is larger than designed
 

Hello! When I import my STL part into star, its far too large. I could scale it down but I'm unsure how much bigger star made the part in the first place. I have all the settings set to default. Could I get some help?

This is an issue with your STL file, not Star-CCM+. Double check the STL export settings, or if that isn't an option, use the rule tool and measure a major dimension then compare to your model. From that, the scale to apply to fix your geometry is easy to calculate. However, there may be some slight point-click error in the rule tool so compare the scale you calculate to common length unit conversions. More than likely you have read in inches or feet as m.
