Then it is probably still active then (I don't recall any changes to pegsless in Release 2021). I will check it here, thank you! 🙏🏻

I am not able to reproduce this problem in egs++ (using the `egs_app` example on a fresh EGSnrc clone). Here is the content of my `mat.dat` file: ``` medium =...

Ok, I am amble to reproduce this with BEAMnrc. Looking into it.

Oops! 🤦🏻 Thanks for pointing that out... (although `@jarkko` is also from Tampere! 😄 )

@blakewalters it seems that there is no `ELSE` to the [relevant `IF`](https://github.com/nrc-cnrc/EGSnrc/blob/a6fc389c6465c949645380976f38a013a639759c/HEN_HOUSE/src/get_media_inputs.mortran#L1332) in `egs_get_media_input.mortran`, handle the case where the density correction file is not specified in the material. This seems...

Thanks for taking the time to report this @karnigen! I will try to reproduce this bug at my end with the input your provided.

I am having trouble reproducing this here (with your second input), as expected. Tried 3 cpus (all Intel though), flags here are `-fPIC -O2 -mtune=native` across the board. Will continue...

I ran 3e9 _histories_ on 256 processors with your second input, and all simulations completed as expected. This is most likely due a rare geometry floating point error. Try offsetting...

Oh, I had misread the second message: > There is no cycle when using original egsnrc compiling options ('fflags': '"-fPIC"', 'oflags': '"-O2 -mtune=native"', 'cflags': '"-O2 -fPIC"', 'cpp': '"-O2 -mtune=native"') (I...
