Yeh, Xing Cai, Hans P. 1 INTRODUCTION Multiscale heterogeneity of geologic media is a rule rather than an exception.

Start with a coarse global uniform mesh for . For a transient problem, this global uniform mesh should be the starting mesh for all the time steps. 2. The global uniform coarse mesh is refined adaptively a few times, possibly making use of the solution of the target equation obtained on the uniform coarse mesh. The result is a medium resolution unstructured mesh covering the entire spatial domain. 3. The unstructured global mesh is partitioned in P subdomains. 4. All the subdomains thereafter refine their own local subdomain mesh independently, each creating a hierarchy of subdomain unstructured meshes.

The coarsest mesh is 323 in size, which is refined by five levels, each with a refinement factor of 2 resulting in an effective mesh resolution of 10243 . The mesh refinement criterion was a simple one: we refined the mesh where the density exceeded a certain threshold. This results in a mesh that can effectively resolve the pellet ablation cloud. 1 Mesh structure in pellet injection. The right image is a magnification of the pellet cloud region showing that this cloud has been adequately resolved.
