For those interested I have completed a basic study on mesh
density and element types using Calculix. The results are
here:

Let me know your feedback and if I should model any other
cases.

Any suggestions for an open source CAD/Tet mesher ? All I
want to do it create simple volumes using protrusions and
revolutions, then tet mesh the volumes. What do you
suggest?

I have written a script that does load path analysis by removing elements that are not in the load path. I would like to improve the visual appearance of the optimized mesh. Any suggestions for either creating a smooth cad geometry from the mesh or modifying the mesh to make it smoother and less...
I have written a brute force script to convert S4 elements
in an Abaqus input deck to S8 ( For CalculiX to use ). The
problem is my script takes upto 20 minutes for a simple
20,000 shell element model.
My pseudo-code is:
First read nodal coordinates for all shells
Next automatically...
I am unable to get some really simple contact models in Calculix 1.6 to converge. Has anyone had success with this new feature? It looks very promising. I can paste my simple input deck if you want to give it a try.

Anyone know offhand the formula for calculating the volume of an 8-noded brick element. I have got all the nodal coordinates but not sure what the formula is? I realize it may not be a simple answer, but will likely involve some vector math..
