Single Coil Gap Feed Problem

Please login with a confirmed email address before reporting spam

Hii all,

I am trying to simulate a simple geometry and I am having problems in giving a particular value of current through the gap feed. The problem is the current density shows always zero.

Can someone help ? I have attached my model herewith.

Thank you.

Regards,
Anup

Hi Anup,

as in your other forum post - the coil feature in your model did comprise more entities than needed,
thereby not creating a regular coil. See my suggestion.

I have deleted all solutions and meshes tho have the model small for transmission in the forum - it solves in 55s.

Best regards,
Sven
