Error importing ICRU-145

[RafaelOScatena]

Hello,

I get an error while loading ICRU-145 mesh phantom, independently of my geometry input block. I made the pegs4 file with the materials...

Thank you in advance,

If you send me an email I can send you a zip file with egs++ input files ready for use with the MCRP phantoms, along with the materials as .density files, and instructions. This will be included as supplementary material in the 2026 release.

[rtownson]

I added the zip file with MCRP materials to the 2025 release assets:

https://github.com/nrc-cnrc/EGSnrc/releases/tag/v2025

Note that it suggests to use git checkout add-mesh-dose-scoring in the instructions. You may wish to use git checkout develop instead to be on the most recent version (before running the installer).

Hi @rtownson , thank you for sharing these files. I am trying to run a simulation. First, I changed the maximum number of media in the array_sizes.h file, then I recompiled the usercode. Now, I am getting this message:

EGSnrc SUCCESSFULLY 'HATCHED' FOR 187 MEDIA.

Error entering get_inputs: Asked for values from 187 to 1 with a max of 100

This implies a bug in the calling routine
Fix it up and try again. Stopping now.

I tried to change REPLACE {$NVALUE} WITH {100}; for 300 in HEN_HOUSE/src/egsnrc.macros, but it didn't work. Can you help me?
Cheers!
