In this work we provide a template-based approach for generating locally refined all-hex meshes. We focus specifically on refinement
of initially structured grids utilizing a 2-refinement approach where uniformly refined hexes are subdivided into eight
child elements. The refinement algorithm consists of identifying marked nodes that are used as the basis for a set of four simple
refinement templates. The target application for 2-refinement is a parallel grid-based all-hex meshing tool for high performance
computing in a distributed environment. The result is a parallel consistent locally refined mesh requiring minimal communication
and where minimum mesh quality is greater than scaled Jacobian 0.4 prior to smoothing.
