This option will generate a Cartesian mesh using a top-down meshing approach. The mesher works by continuously refining the initial grid in a binary fashion in each dimension, and eliminating the non-volume cells, up to the specified maximum refinement. The Cartesian mesher does not require an existing surface mesh and will ignore meshing parameters defined to control local surfaces. The mesh will be refined until the finest cell size does not exceed the Max element size specified in Global Mesh Setup or the Surface Mesh setup.
