expected, not when the relative flow is impinging on the endplate
where flow separation is unlikely. Option 0 is suitable for
strip-theory-only members, whereas option 1 might be better suited for
hybrid potential-flow members with drag force. Note that option 1
hybrid potential-flow members with drag force. Note that option 0
uses a leading coefficient of 1/4 when computing the drag force, while
option 2 uses the more common leading coefficient of 1/2 since drag
option 1 uses the more common leading coefficient of 1/2 since drag
is usually only applied to one of the two endplates of the member
instead of on both.
