RE: [fluka-discuss]: Specialized source routines

Dear Carl
Note that there are some built-in source routines which allow you to sample from so called extended volumes (or in fact shells). If your source shape is a cylindrical, spherical or Cartesian shell then you can use the built-in source to define the position. Note that it does not have to match exactly a region of your geometry….

More details can be found in the material of the last advanced FLUKA course (agenda will all course material)

In particular the presentation on advance sources

If you have a different shape then you need to write a source routine (to specify the logic of the spatial distribution, energy, direction of the primary particles….) and create your own executable. The routine is called adding a SOURCE card in your input.

Have a look at the manual and at the course material on writing user routines:

Hoping this help…

Subject: [fluka-discuss]: Specialized source routines

I am interested in being able to model a source uniformly distributed throughout a volume, e.g., a source of 0.5 MeV electrons in a volume of water.

It seems this can be done with a specialized source routine and perhaps has already been done:

I have not found a central repository of Fluka resources where something like this might reside.

Is there a chance a suitable source routine already exists?

Thanks, Carl
