It's hard to say without seeing your mph file, but if I was to venture a guess, it would be that the first voltage applied is too large. Try ramping up the voltage more progressively. If that's not the issue, consider uploading your mph file.
Best,
Jeff

                                                    I am doing pull in voltage study using stationary study using auxiliary sweep for Zset. in stationary solver i have Fully coupled linear solver as Direct, that is where I am getting the error "Failed to find a solution for the initial parameter.
Maximum number of Newton iterations reached.
Returned solution is not converged.
Not all parameter steps returned.
