I am using Abaqus Python scripting to model the following sketch. The dashed green line (Curve_0) is a half circle and the yellow one (Curve_1) is a circle arc. The center point of Curve_2 (which is another circle arc) named Cen_2 must be located on Curve_1. Assuming the x coordinate of Cen_2 is x_Cen_2, its y coordinate can be easily calculated using the equation of Curve_1. However, this point is not located on Curve_1 which might be due to some graphical complexes or any other reason (please see the figure). In this regard, I have tried several approaches to solve this issue. But none of them has worked. I would appreciate if anyone could kindly advise.
I obtained the same effect for the simple case (see the figure). It is a round-off error not connected with the script. It is helpful to use Add Dimension and Edit Dimension tools to see real distances.
