Reply To: How Autodyn handle gas phase

[Shuan-Tai Yeh]

Hi Chris,

Thank you for providing such valuable insights. Your explanation regarding those EOS in Autodyn is greatly appreciated. I do have a follow-up question regarding simulating air (background) during events. While I understand Autodyn offers an ideal gas EOS for air, I'm curious about whether the governing equations (moment, energy) still rely on stress and strain. This aspect is a bit confusing me, especially in relation to obtaining gas properties from solid properties.
