I’m currently working on the creation of a parametric volute with an overhung section.
I have almost completed my model. However, after having exported my geometry to an external CAD in step format, I noticed that a loss of tangency occurs at the interface between the outlet duct and the scroll, in correspondence of the largest section.
For the creation of the outlet duct, I followed the tutorial available in CAESES: I used the fillet surface (with both tangent factors equal to 1 and edge sampling strategy with 50 nodes) to smoothly connect the outlet section with the scroll, after having defined two auxiliary surfaces.
Is there any correction I can apply to overcome this problem?
Thank you very much.
