Neumann boundary condition not allowed with skew unit cell
« on: January 27, 2015, 09:36 »
I have a structure with Gate on Top. As I used Neumann Boundary Condition in the direction of Gate and run the script I get the following error? Why is it this the case? 

NLValueError: Neumann boundary conditions are not allowed with skew unit cells.

We have to use Neumann boundary condition for gated device, right?

The error message tells you what is wrong. It's always best to work with orthogonal cells if you are using gates and dielectrica. It's not strictly necessary, but almost.
