So I just finished associating the mesh with the geometry on my 400 faces or so and Abaqus successfully wrote out the input file (which I still have to edit so that if actually runs)! The point is I am hours (perhaps days) away from a truly fantastic carburizing simulation!

A first fruition of my work!
I'm working on this complex model of half of a ring gear. I've been working on it for several weeks, probably more like months. The last two weeks I've been working on associating the mesh with the geometry which is a problem with bottom-up meshing sometimes. In short, the mesh made up of a finite number of elements is not the same as the geometry that you planned. They may look the same but when you take a closer look you will see slightly off angles in the range of .1 or .2 degrees away from parallel. There are also curves that are approximated as strait lines that you need to associate with the geometry. So you must select Mesh > Associate Mesh with Geometry..., then select the feature (face, edge, etc. ) on the geometry, then select the mesh (using "by angle" instead of "individual" works better but keep the degrees like .3 or something low) then click done and the face or other feature you selected on the mesh is now associated with the geometry.
