Error in time dependent study when periodic electric current applied

Hello everyone,
I think I somehow managed to define a periodic signal by combining a rectangle signal and an analytic function.
In order to make use of this signal as an electric current input, I multiplied the analytic function (no units) with my current parameter (25 Amperes). So, under Terminal I have " I*an1 " as applied electric current.
When I try to simulate a time dependent study, I get an error.
I attached 3 screenshots.
What am I doing wrong?
Thank you,
Bartu

Hi Bartu,
That Jacobean error has come up with me too, there are some possible tweaks one could perform, but they depend on the physics. Could you attach the model here so I can take a look? I might be able to help!
