Thank you dear Gulin.

As you say if it is because of fde solver? If yes what can I do?

I also tested 10 nanometer step and higher. I wanted to know that how much isĀ  my designed structures error threshold .but I couldn't find any area that my answers become true on it . The mode results changes in every point

Thanks for answering this post. I will write new post for my new questions.
