In this blog we will focus on a problem that happens when working with input files. Not exclusively but it is often encountered when performing geostatic finite element analysis (FEA). Briefly, the problem is that the analysts work with finite element models where no geometry is available but only a mesh. Working without geometry brings an important limitation: re-meshing and therefore local refinement is not possible.

But why would we need re-meshing in the first place?

Meshes next to a fault might be fine enough to capture the necessary detail. However, meshes away from the region of interest do not need to have the same level of refinement. If our domain extends through a couple of kilometres we would have extremely large meshes.
