Hello,

I am trying to simulate the sudden gas expansion of compressed H2 gas in open atmosphere using CESE solver in LS Dyna.

How can I insert CHEMKIN file as input to CESE solver? 

Is it possible to include real gas properties in LS Dyna using NIST database?

Regards,
Atish

Please see the CHEMISTRY cards in the multiphysics manual: https://ftp.lstc.com/anonymous/outgoing/web/ls-dyna_manuals/DRAFT/DRAFT_Vol_III.pdf, especially CHEMISTRY_MODEL. Also, CESE_INITIAL_CHEMISTRY may be helpful. Any CHEMKIN-compatible data sets should work.
