getposoncircsection()

subroutine curvetypemodule::getposoncircsection	(	real(dp), dimension(:,:), intent(in)	Pos,
		real(dp), dimension(3), intent(in)	DefPrev,
		type(curvepointtype), intent(inout)	CP1,
		type(curvepointtype), intent(inout)	CP2,
		real(dp), intent(in)	thickness,
		real(dp), intent(in)	width,
		real(dp), intent(in)	radius,
		logical, intent(out)	isInDomain,
		real(dp), dimension(:,:), intent(out)	PosOnCurveG,
		real(dp), intent(out)	Xsi,
		real(dp), dimension(:), intent(out)	Def
	)

Checks if a given point Pos is on a circular curve segment.

The curve segment is defined from two points CP1 and CP2. If the point is found to be on the segment, compute the local position and orientation (Xsi and Def) of the point w.r.t. to the curve segment. The curve tangent vectors at the curve points are also updated based on current triad configuration (for use in the subsequent corner test).
