Hi,
As of now you cannot define two pre-built distributed sources in a single
input file. Thus, the remaining alternatives are:
1) Run simulations with each of the sources (using the BEAMPOS cards), and
combine the results according to the weight of the sources, or
2) write a user subroutine (source.f) that handles the definition of each
of the volumetric sources as well as the relative strength of each.
Probably option 1 is going to be easier and also allows for recalculation
of results as a function of the relative strengths, as long as you keep
the individual output results.
Regarding c user routines, Paola announced that those are being prepared
and will be made available shortly.
