Hi. i am a high school student and i am trying to code simple algorithm for 2 dimensional convection-diffusion problem using FVM in Python. But, the grid in the center seems not to be defined in result contour even i define all range of grid. And the code block below is the code that i used to define grid.

Nx, Ny = 7, 9
dx, dy = 1.0, 1.0
Lx, Ly = Nx * dx, Ny * dy
