An option to computer the cell volumes similar to Serpent 1's:
would be excellent for verification of inputs and dimensions. This would also be helpful for printing out the interface volumes before had, too, for post-processing. I currently have a separate binary that I use where I modified printinterfaceoutput.c to do that for me. I notice there's a MATLAB output option, but that's pretty memory heavy for large problems - and I don't need it printed out with every run.
