How to divide octree levels

When I use Octree in SimPEG, I find that I do not know much about the mesh refinement. In the graph I draw with Octree levels in the example, the meshes are too dense in the middle. Can you tell me how to divide this level

Hi @peterfen-eng,

Apologies for our late reply! We have recently updated the discretize documentation to include more examples and tutorials on mesh generation. Please see this example and feel free to post further questions if this does not address your question: Tree Meshes — discretize 0.8.0 documentation
