Hello Vasilis,

I am sorry for bothering you again.

I have modified the source.f file, but I am still not getting the extended source. Also, how can I be sure that I am reading the values correctly?

In this case you have to make the distribution yourself.
When you push a particle in the stack at some moment the standard source.f
has

* Particle coordinates
      XFLK (NPFLKA) = XBEAM
      YFLK (NPFLKA) = YBEAM
      ZFLK (NPFLKA) = ZBEAM

you can change it to something like in your custom source.f
      XFLK (NPFLKA) = XBEAM + DX * FLRNDM(xxx)
      YFLK (NPFLKA) = YBEAM + DY + FLRNDM(xxx)
      ZFLK (NPFLKA) = ZBEAM

where DX and DY you define somewhere above in the source.f
with the width x length of your source

Cheers
Vasilis

So if I want to use a a user defined source I should change the beam definition inside the source.f or how?

It doesn't work since you have added also a "SOURCE" card
The SOURCE card tells the code to call the user routine source.f
and not the predefined one with the cards.
Comment the SOURCE and it will work.

Please always use reply-all to keep the discussion on the list.
Can you send your input file to check what is wrong.
