Electric interference

Dear Experts,

I got the following error message:

  • Parameters: "time","0"
    The following feature has encountered a problem:
  • Feature: Time-Dependent Solver 1 (sol75/t1)
    Failed to find consistent initial values.
    Last time step is not converged.

The physics: Electric currents
The equation I used: (the polarity changes)
Io*sin(2*pi*f1*t)
- Io*sin(2*pi*f2*t)
Io*sin(2*pi*f1*t)
- Io*sin(2*pi*f2*t)

See at physics.png
Note: though the are two current sinks under the electric current, these are Current source as well. (I know, in Electrochemistry Module there is a designated module to current sink, but I do not have access to it. )

The solutions that did not work: - A Stationary step was added before the Time dependent study
- Using the following equations to avoid the value 0:
- Io*sin(2*pi*f*t)*(1 - exp(-t/tau)) - Io*sin(2*pi*f*t)*(t<ramp_time) + Io*sin(2*pi*f*t)*(t>=ramp_time)

  • Changing the time range
  • redo the whole study/physics
