ife_variables

Module containing global variables relating to the inertial fusion energy model

Default IFE builds and material volumes are those for the SOMBRERO device. The 2-dimensional arrays have indices (region, material), where 'region' is the region and maxmat is the 'material':

'region' = 1 radially outside chamber
'region' = 2 above chamber
'region' = 3 below chamber

`MAXMAT = 8` `module-attribute`

Total number of materials in IFE device. Material numbers are as follows: - =0 void - =1 steel - =2 carbon cloth - =3 FLiBe - =4 lithium oxide Li2O - =5 concrete - =6 helium - =7 xenon - =8 lithium
