Source in arbitrary shaped geometry

Dear Experts,

I have an irregular shaped volume. I want to model uniform distribution of source particles within this volume. Is it possible in FLUKA ?
Note that source is a spectrum of photons.

In source.f, can I dirrectly assign a geometrical volume or region ?

Kindly suggest me how to do this.

Thanking you in advance.

Dear @ArghyaC,

To model a geometrically complicated source, I would suggest you to use the source_newgen.f routine. You can find plenty of documentation in the slides from the last courses and on this forum.
