Thank you, Vladimir!

We think that there isĀ  a straightforward mapping for TID (energy dep) 
and volume fluxes/currents, but I am struggling with a surface current.

GRAS has examples of mesh tallies calculating flat surface current/flux 
(under tests/mesh_scoring), but it produces zeros (I had to comment out 
the line setting up the units as GRAS crashed for me there).

Another user (copied) gets this message:

[GRASAnalysisModule::SetUnit] ERROR: No conversion factor available for 
unit: mm [GRASAnalysisModule::SetUnit] WARNING: Keeping unit: Looks like 
Sergio Ibarmia Huete developed these scorings (flat surface/flux) and I 
hope to get in contact with him. If you happen to know his email, could 
you share with me off list? Best, Svetlana
