1. ### Ansoft Maxwell Problem in Assigning Excitation of Current

As the picture showed, when I assigned a current excitation on the coil plane( pink one in image), Ansoft Maxwell alert ”current1 can not assigned on the entity of type face". This is incredible as I take the process completely based on the book!
