Dear All,

I'm working on the eddy current sensor simulation with the different target material. According to my model, I cannot apply the coil excitation frequency lower than 20 kHz, for example, 1,000 Hz. The results do not converge.

Please advise how to adjust the simulation model to solve this problem.

Many thanks,

Siripong

Siripong,

This is so called conductivity scaling effect - set air conductivity to some small number, say 1 S/m, then Compute.

Regards

Sergei
