Source in arbitrary shaped geometry

[ArghyaC]

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.

Volumetric source of complex geometry

Dear Fluka experts, I’m trying to model volumetric source of complex geometry which is a cylinder with a hole (as shown on the picture). I’ve tried to describe it mathematically by using source.f routine but the result was not satisfying. Is it possible to describe this geometry of the source without using source.f routine? Can I use MREG or MMAT in the source.f user routine? Thank you in advance, Alexy [Source]

Cheers,
