Hello

Hello,

I’m trying to install egsnrc on my 32-bit ubuntu. However I can’t launch the installer (./EGSnrc-configure-linux) and I get the error “bash: ./EGSnrc-configure-linux : cannot execute binary file. Exec format error”. I have given the installer permission using chmod +x. It seems that the error is that the installer is a 64-bit program and my computer is 32 bit. And therefore I can’t install it. I also can’t find any information about a 32 bit version of EGSnrc.

Has anyone had this problem? And how did you solve it? Or does anyone know of a solution?

Any help would be much appreciated. Thank you.

How would one read a phase space plane to extract fluence values along with corresponding (x,y) positions, as an ASCII file or other human-readable format? Is it also possible to export the “List” option from BeamDP instead of only being able to view it on the screen? We tried to use the BEAMdp command line tool but it appears that it does not include all particles past 10 000. Would this be a beamdp.macros issue?

Thank you for your time.

Hi all :)

Hi all 🙂

I’m stuck debugging a BEAMnrc simulation that ends up in some kind of endless loop for some seeds. So what I did was tracing back seeds where the simulation ended up in the endless loop and printed the interactions.

Now I know, that the simulation gets stuck after a Moller interaction somewhere in my flattening filter, maybe someone knows a possible reason? Sadly I cannot share the model.

Best wishes

I’ve been thinking about installation and the configure script.

I’ve been thinking about installation and the configure script. In the modern era is there a point to all of the checks the configure script runs? i’m finding the configure script long and hard to parse.

Here are a few things I would like to add:

Support for detection of multiple versions of gcc

Support for building with Clang/Flang

(no I don’t expect the code to support this new compiler yet)

Consistent compiler detection

Right now cc and cpp are quite different.

if desired setting consistent optimizer settings accross fortran c and cpp compilers

I was wondering how to use BEAM/DOSEnrc to calculate dose in water phantom voxels that is only from primary photons.

I was wondering how to use BEAM/DOSEnrc to calculate dose in water phantom voxels that is only from primary photons.

I’m basically just looking to calculate TERMA in the water phantom and I don’t want any secondary interactions to take place. Only photons that have hit a target in my BEAM model and made it (interaction free) to voxels in the phantom should be used in dose calculations.

Thank you!

I have prepared a phase space (PHSP) file for 1×1 cm^2 field size for a commissioned LINAC and used that PHSP file in dosxyznrc to check dose distribution in water phantom.

while running the job I am facing a warning:

Warning Used all particles from source file

Restarting from first particle infile

I want to ask how can i avoid this warning and does that can potentially affect our results.
