Validation Meshes

Since the dissertation includes a mesh validation study, a number of meshes were generated from the anatomical data, using Abaqus. The pertinent properties are given in the table below, with the mesh I ultimately chose highlighted. (The filenames are what they are for uninteresting reasons. In my dissertation I referred to the “46,9490-element mesh” to avoid the sloppy nomenclature.)

You can download the meshes below. I've simply provided the Abaqus .inp files, which you can open in Abaqus (or FEBio, or a number of other programs). You can also just open it in a text editor; the file format is fairly transparent, and further documentation is available online. You can also use the software described in the Assigning Properties section to process these files.

ValidationMesh4? You won't find mention of that in the dissertation. I didn't leave it out for any principled reason; I just could never get the solver to converge for that mesh (maybe just for computational reasons that will be out of date in six months). It has a lot more nodes and elements than ValidationMesh33.
