MOSCAP results at final voltage dependent on starting voltage?

I have been running the MOSCAP application to solve for the electric field in an oxide under different conditions.  I have found that the electric field at final voltage varies based on the choice of starting voltage in the environment tab.  Is there a workaround for this problem?

    The dependence on the starting bias can be seen in multiple devices when using the drift diffusion model in various implementations.   My suggestion would be to always start from equilibrium and begin perturbations from there.   The equilibrium solution should be in general be the most trusted one.
