Reply To: How to make a mapping image E=f(x,y)

Thank you Guilin.  I am trying to get the figure underneath similar to How to find out Phase shift of transmitted wave varying radius vs wavelength (ansys.com).

However, I am not sure how to export E field as a result in sweep. Should I use e-outlined or other analysis functions to export E strength? Thank you!
