This is a great, never-ending detective story where there are always new suspects for you to nail :) Perhaps a letter(s) to PRL might help raise the profile of your model? I'm suffering from the paradox of choice as to what's the best open source tool to code a solid geometry earth model simulation? I've not been able to find out what nullschool's programmed in. Fenics and Blender are 2 other possibles.
