WebChapter 2: Adaptive Mesh Refinement Motivation . In the numerical solution of partial differential equations (PDE) a discrete domain is chosen where algebraic analogues of the PDEs are solved. One standard method is to introduce a grid and estimate the values of the unknowns at the grid points through the solutions of these algebraic equations. Webusers can generate pure hex meshes using one of several mesh methods, depending on the type of model and whether the user wants a pure hex or hex-dominant mesh.
