3D Curve operation failed - NACA airfoil
 

Hello everyone,
I am currently studying the effect of ice accretion on NACA23012 airfoil, using ANSYS Fluent and Design Modeler to generate geometry with Excel files.


I managed to import coordinates with an Excel file for the clean airfoil easily (no ice).


But when I try to import the modified clean airfoil Excel file corresponding to the coordinates of an iced profile (horn ice), I have the following Error on Design Modeler:


Error: 3D Curve operation failed (self-intersecting?)
Context: Geometry Engine, while generating Feature Curve 2

The excel file generating the error is here attached.


Could somebody help me, please?


Thank you very much,
Alice Petit
