Getting volume numbers with materials from h5m file

[drshi...@gmail.com]

Hi all

Just wondering if anyone has suggestions for getting some data from a DAGMC.h5m file with Pymoab

I am looking for a method of getting the volume ids with their corresponding material tags from a DAGMC h5m file using pymoab

I have a method of getting volume ids from a h5m file

https://github.com/fusion-energy/openmc-dagmc-wrapper/blob/c99ecff48ad9ff09ef36a86209d156f8b397b8ae/openmc_dagmc_wrapper/utils.py#L102-L131

I also have a method of getting material tags from a h5m file

https://github.com/svalinn/remove_dagmc_tags/blob/c529c688959647faaebba0a932f96c0c10891f61/remove_dagmc_tags/core.py#L11-L56

I just can't do the two operations together to produce a list that contains both volume ids and their material tags like this

mat tag 'steel' volume id 1

mat tag 'steel' volume id 2

mat tag 'water' volume id 3

mat tag 'gold' volume id 4

Many thanks

Jon

Hi Jon,

I think you have almost all the pieces.

I threw together this as better than pseudo-code.  It has not been tested and is sure to have bugs, but it gives you the basic process.

Thanks Paul

The code you made was super useful. with your help I made a pip installable package.

dagmc_h5m_file_inspector is a minimal Python package for finding DAGMC volume ids with their material tags.

Just in case this is useful to anyone else here is a link

All the best
