2. I compared a free electron in a 10nm x 10nm x 10nm closed box with an analytical formula and got a very different result

   Q&A|Closed | Responses: 3

   I expect to get 0.011eV for the ground state quantization energy. The tool gives me 0.040eV.

   Is it a problem in my interpretation of the results or the tool is wrong?
