Thank you Aniket, but I want to say that the problem I am experiencing is caused by lsdyna, and I hope you can report to the relevant department to fix the issue where materials using the keywords *MAT_ELASTIC_PLASTIC_HYDRO and *EOS_IGNITION_AND_GROWTH_OF_REACTION_IN_HE will automatically detonate without any outside influence when lsdyna version is higher than R12.
