The “tangent vector field” option should only be used with mesh refinement set to conformal variant 0, 1 or 2. That might be the reason you are getting error. 

For the second question: Change the radious of “model” to 100 nm and rerun the simulation. Then visualize Ep from xz_filed. The results in website will be updated soon. 

50 nm:

=======>'Ep”>Ep’ from the “xz_field” 


100 nm:

=====>'Ep”>Ep’ from the “xz_field”



Note: Try to post one question per post. It will be easy to resolve and avoid confusion in attached screenshots. Ansys Insight: Ansys Innovation Space–Forum and Feed
