[FTX]

I implemented an equation of state(Air) with the autodyn subroutine and found an anomaly in the multi-material Euler solution.

[FTX]

In the figure above, the Euler grid on the left side of the steel plate shows an obvious abnormal pressure value at the boundary between hmx explosive and air. However, there is only air in the Euler grid to the right of the steel plate, and the pressure values at the front of a steel block moving to the left look normal.

I found that when an Euler grid includes both air and explosive material. The internal energy of the air material is very low, even the internal energy value is 0.

Hi,

This is the type of question that we will not answer in the public Student Community other than stating: “Unfortunately this question is beyond the scope for ANSYS employees to answer on a public forum, so hopefully other users can chime in.”
