I am trying to design a helical coil and I have a couple of problems. 

1) I want rectangular cross-section not square. 
2) The geometry throws an error if the radius change is not at least twice the radius of the cross-section! How is the radius change defined---? I want the turn to turn clearance to be small- say for a rectangular cross-section of 10mm by 5 mm and in-between each turn only 0.1 mm gap. Is there a way to manually make this design in ANSYS?

Picture 1 (what I have right now)- Turn-turn gap at 6mm (measured) for a square cross section of 9.9 mmx9.9mm. 
What I want: Turn-turn gap at 0.1mm for a rectangular cross section of 9.9 mmx4.5mm.

3) Say I have such two copper flat spherical coil axially lined up. How do I calculate their capacitance?

Hi,

Please use Draw>>User Defined Primitive>>SegmentedHelix>>RectHelix to draw it. You can define the width and height of the cross-section as well as other parameters.

For capacitance, you can use eletrostatic solver, assign voltage to the coils and get the capacitance between them.
