Hello OF users!

I have some problems when I use the ellipse edge,

I want to know what is the meaning of this funciton

return eFactor_*sqr(x1_*c + y1_*s) + sqr(x1_*s - y1_*c)
- eFactor_*sqr(x2_*c + y2_*s) - sqr(x2_*s - y2_*c);

in the header field of rotEllipse2D.H in dirction
/applications/utilities/mesh/generation/blockMesh/curvedEdges

Thanks in advance!

eFactor_*sqr(x1_*c + y1_*s) + sqr(x1_*s - y1_*c)
- eFactor_*sqr(x2_*c + y2_*s) - sqr(x2_*s - y2_*c)

this funtion is not Monotonic function in[0,piByTwo] and [piByTwo,pi],

so we must find a Monotonic function instand
