D3plot: missing material ID

[awoimbee]

Hello,
Some fields are not handled by this lib: https://www.dynamore.de/de/download/manuals/ls-dyna/archiv/ls-dyna-database-manual

What interests me is material ID, but it seems like this lib is also missing geometry data and more (see linked PDF).

At first i thought the solution was to parsed history_vars, but the more I read about d3plot, the more I'm lost 😄 :

• https://www.dynasupport.com/howtos/material/history-variables
• https://qd-cae.github.io/qd-cae-python/build/html/qd_cae_dyna_FEMFile.html#qd.cae.dyna.FEMFile.get_element_history_vars

We read the material aka part ids don't we?

[awoimbee]

Materials and part ids are different
I see references to mattyp and part_material_type in this lib, but only in the d3plot writer, not in the reader

[codie3611]

Hmmm I'm pretty sure we read any kind of ids there is for either parts or materials. Maybe I confused it somewhere in the terminology. Maybe check the id arrays if there is something. The d3plot has multiple id arrays redundantly. part_material_type is just the material type number not the material id.

Reading material data from d3plot is not crucial in my view. I have never searched for material type through d3plot but always from input k file. I think material ID is important for the solver but not crucial for the post-processing. Please correct me if I am wrong. 😬
