Dear all, Visualizing current flow in 3D systems is challenging. Kwant provides built-in features for 2D systems, but does not support 3D current visualization. To still gain some insight into the current flow in my 3D nanowire system, I analyze the current on a single 2D facet of the nanowire. However, the resulting current distribution appears inhomogeneous, which is surprising given that the physical system is homogeneous. I have attached a minimal example (current_visualization.py) that demonstrates the issue. Has anyone encountered a similar situation? Could this be a visualization artifact, or might it indicate an issue with how the current is computed in 3D systems? Any suggestions or insights would be greatly appreciated. Best regards, Thomas
