Unsymmetric data from symmetric bounday

      Hi,

      I noticed my data from simulation with symmetric boundary condition is not symmetric. For example when I used the symmetric boundary in x and y axis, the center of the data is off. Following is the data for Ex field. There are 85 points in every axis. You could see instead of symmetric at the middle point x = 43, it is symmetric at x = 42.5. Of course I can change it to symmetrical manually, I just wanna make sure if that is a bug from the software, or it is something wrong in my simulation?

       

      Thanks for you help!

      Due to discretization, it cannot be at the half of the cell. Please email me back if you still have questions.
