Hi, I wanna simulation the process of concentration gradient driven electrical potential. In this case, I choose the physical field as Nernst Planck Equation or Tertiary Current Distribution (TCD). The key issue for the simulation is the time-dependent diffusion process driven by concentration gradient. However, when I use transient study, it always says "Failed to find consistent initial values. Last time step is not converged."

Anyone can help me with this issue?

Thank you for your help.
