How to plot matsum energy in hypergraph for a specific assembly of a full vehicle model(LS-DYNA)?

Rahul Ramesh Zambre

I have one full vehicle model(LS-DYNA). Which has around 2000 parts.

in the vehicle there are various assemblies (e.g. door,tail gate, biw,….)

now i want to plot matsum internal energy for these assemblies separately.(assembly contains many parts).

FYI

plotting matsum internal energy one by one for every part is not possible for me because of high number parts .

i know the part ids in the assembly.

thanks…

Hello @Rahul Ramesh Zambre ,

did you check the possibility to export from LS Dyna directly this MATSUM at the assembly level.

I a ask because I am not familiar with LS Dyna, but in Radioss we can define Assembly entities

(/SUBSET) on top of parts, and to request outputs directly on these assemblies (/TH/SUBSET).

As Explicit solver were designed from the beginning to consider large assemblies, I would be surprised LS Dyna does not propose such an option

Best Regards,

Michael
